This case arises , out of an accident which took place on the Trans Canada Highway 1 on April 18, 1970. The plaintiffs, Alexis McLaughlin, her daughter Mary Ann McLaughlin, and her niece Jocelyn Wujcik Wolfe, were travelling in a Ford truck on which a camper was mounted. Also present in the vehicle were Margaret Wujcik, sister of Alexis McLaughlin, and Catherine McDonald. 2 While they were travelling at about forty-five miles per hour, there was a blowout in the left rear tire; the truck went out of control and rolled over, and the camper became completely detached from the body of the truck. Wolfe, who was riding in the camper at the time, was seriously injured; the other plaintiffs sustained lesser injuries. The defendants in the case are Ford Motor Company (Ford), manufacturer of the truck, and Harold R. Donahue (doing business as Donahue Mobile Homes), the dealer who assembled the truck and camper unit and sold it to James McLaughlin, the husband of Alexis McLaughlin.
The original declaration, filed April 3, 1972, alleged injuries "by reason of the negligence of the defendant [Ford]... in the manufacture of said motor vehicle and/ *348 or the equipment and/or apparatus connected therewith ____” 3 The declaration also alleged in separate counts a breach of warranty by Donahue.
On June 2,1975, at the beginning of the trial, the plaintiffs moved to amend their complaint (see Mass.R.Civ.P. 1A [3],
The case was submitted to the jury with interrogatories (Mass. R.Civ.P. 49[b],
Ford’s Appeal
It is now accepted by both Ford and the plaintiffs that the jury could have found, as they did, that the blowout was caused by a combination of overloading the vehicle and underinflation of the left rear tire. Rather, Ford disputes the jury’s finding that it was negligent in failing to provide an adequate warning of the danger that might arise from these conditions. It argues that, as a matter of law, adequate warnings were provided by the operator’s manual furnished with the vehicle and the "rating plate” affixed to the door of the vehicle which gave (as described in the manual) the "recommended maximum gross vehicle weight rating.” We disagree.
The duty of the manufacturer to warn of the dangers in the use of his product is well established; it is applicable to hazards involved in the use of properly designed products by users to whom the danger would not be apparent.
Farley
v.
Edward E. Tower Co.,
A jury question was presented whether the manual and the rating plate were sufficient to bring home the danger of a serious accident, which might result from a blowout, to the ordinary buyer of the truck who might use it with a camper.
Mealey
v.
Super Curline Hair Wave Corp.,
Upon examination of the references in the manual to which Ford points, the jury could well have found that these references to the "Recommended tire pressures” and "Tire Pressures” — like, e.g., the accompanying references to "Maintenance recommendations” and "Cooling Systems,” respectively — were designed to give information as to the most efficient use rather than alert the user to potential hazards. We find unpersuasive the emphasis placed by Ford on the statement under the heading "Tires and Tire Care”: "For reliable vehicle control always maintain the recommended difference between front and rear tires.” The jury could well have found that this suggestion, if relevant at all, was too oblique a reference and that a more explicit warning was required. 7 *352 Also, the jury might well have taken into consideration that this truck was built as a "camper special” (so designated in the manual) to be used by consumers having no experience with trucks.
Ford’s contention, phrased in terms of proximate cause, that the plaintiffs did not introduce any evidence that an adequate warning would have reached them, is unpersuasive. An adequate warning is by definition one that would in the ordinary course have come to the user’s attention. The failure to give such a warning therefore permits the inference that it would have alerted the user to the danger and forestalled the accident. The jury were free to draw such an inference absent some negating evidence binding on the plaintiffs. The burden was on the defendants to come forward with evidence tending to rebut such an inference; the plaintiffs were not required to refute a hypothesis which was never raised. "The very reason that the law imposes a duty to give notice in a particular case is the assumption that, because of the danger not commonly known to users, 'a warning is needed.’. .. That the plaintiff fell outside the common class should be the defendant’s burden, not the plaintiffs.”

Silverman,
We also reject Ford’s attack on the action of the judge in permitting the complaint to be amended to include a claim of inadequate warning. Allowance of the amendment at the beginning of trial on June 2, 1975 (see Mass.R.Civ.P. 15[a],
Nor do we see any error in the allowance of the plaintiffs’ motion to conform the pleadings to the evidence (Mass.R.Civ.P. 15[b],
Donahue’s Appeal
Donahue makes only two contentions which we need consider
(Lolos
v.
Berlin,
1. We hold that Wolfe, the buyer’s niece, is a "person who is in the family ... of his [Donahue’s] buyer.” G. L. c. 106, § 2-318. The interpretation of § 2-318 in this respect has not come before the Supreme Judicial Court or this court. We are persuaded by the analysis in
Miller
v.
Preitz,
This construction is consistent with and finds support in
Dodge
v.
Boston & Providence R.R.,
Further, the application of § 2-318 to such persons as Wolfe seems to us within the legislative intent to liberalize the "technical rules as to ‘privity’ ” (Comment 2 to § 2-318 of the Uniform Commercial Code, as appearing in 1A U.L.A. [Master ed. 1976]) consistent with the "remedial nature” (
2. In the hands of an ordinary user the truck and camper unit with nothing more than the inadequate warnings furnished by Ford created, as the jury found, the danger of a blowout when used "for the ordinary purposes for which such goods are used.” G. L. c. 106, § 2-314 (2) (c). Donahue’s sale was thus in breach of the warranty of merchantability, for a product is "unmerchantable if sold without a suitable warning.”
Casagrande
v.
F.W. Woolworth Co.,
Other courts have also held that inadequate warnings may be the basis for a claim of breach of implied warranty. In
Gardner
v.
Q.H.S. Inc.,
Judgments affirmed.
Notes
We accept the assumption of the parties that the law of Massachusetts applies. No conflict of laws question has been raised.
Counts in the declaration on behalf of Margaret Wujcik and Catherine McDonald were dismissed by stipulation at the beginning of the trial.
On May 31,1972, the plaintiffs specified the cause of their injuries as: "There was a tire rim failure while the camper trailer was travel-ling on the highway.” They had also been ordered to specify how the wheel was defective and answered: "Bent tire rim, inability of wheel to withstand riding strain. I intend also to rely on such evidence of negligence as shall appear in evidence during the course of trial.”
At the end of the trial the judge allowed, again over Ford’s objection, a further motion to amend the complaint which struck the portion italicized above and substituted instead "and/or in its failure to give adequately information to potential users of the vehicle and camper or to take reasonable measures to make known to such users the risks and dangers with respect to what could occur as a result of underinflation of tires or the imposition of weight in excess of the gross maximum weight of the vehicle.”
The jury found specially that the cause of the accident was not either overloading or underinflation separately.
Ford’s expert pointed out that the underinflation and overloading complemented each other to create a distortion in the tire ("overdeflection”) which resulted in the failure of the rim.
We also note that the suggestion, "Before driving each day, glance at all your tires. If one looks softer than the others, have all pressures checked” might well have been considered by the jury to be misleading in view of the testimony by Ford’s expert that the substantial underinflation in this case would not have been detected except by an expert. Compare
Schaeffer
v.
General Motors Corp.,
We see nothing of any consequence in the isolated bit of testimony by Mrs. McLaughlin that whenever she went on a trip she had the camper checked at a garage. At most it admits of speculation that the serviceman was negligent, but that would not absolve the manufacturer.
H.P. Hood & Sons
v.
Ford Motor Co.,
The restrictive effect of specifications furnished by the plaintiffs prior to the new rules does not abridge the judge’s discretion under rule 15. See Transitional Rule 1A[2],
The injection of this claim appears to have been prompted by information furnished to the plaintiffs’ counsel by Ford shortly before trial, that its experts would testify that the rim of the wheel failed by reason of "either an overload condition and/or underinflation condition with respect to the tires or a combination of both” and by an examination of the operating manual also furnished to the plaintiffs by Ford shortly before trial. The summary of expert testimony was given to the plaintiffs on April 11, 1975, pursuant to an order of the court dated January 14, 1975, that it be furnished in thirty days. Thereupon on April 17,1975, the plaintiffs moved for the production
*354
of the operator’s manual and other documents. The motion was allowed on May 1, 1975. According to the defendant’s brief, the documents were given to the plaintiffs on May 7. The court further ordered, on April 11, 1975, production of additional documents and photographs supporting the opinion of one of Ford’s experts; these were provided on May 15,1975. Contrast the evidence of delay by the moving party in
Castellucci,
Ford does not claim that it thought that this cross-examination was directed to an issue already in the case. Indeed, the plaintiffs’ cross-examination could have come as no surprise in view of the information Ford had furnished the plaintiffs and the complementary effect of overloading and underinflation to which Ford’s experts testified.
That statute read at all times material: "A seller’s warranty whether express or implied extends to any natural person who is in the family or household of his buyer or who is a guest in his home if it is reasonable to expect that such person may use, consume or be affected by the goods and who is injured in person by breach of the *356 warranty. A seller may not exclude or limit the operation of this section.” The statute was amended by St. 1971, c. 670, § 1, to eliminate the requirement of privity as a defense "if the plaintiff was a person whom the manufacturer, seller or supplier might reasonably have expected to use, consume or be affected by the goods.” (See also St. 1973, c. 750, which amended this proviso by adding the word "lessor” after "seller.”) The requirement of foreseeability has thus been a part of the statute at all times; and Donahue makes no argument that Wolfe was not a foreseeable traveller in the McLaughlins’ camper.
The court instructed the jury in accordance with this warranty rather than G. L. c. 106, § 2-315 (inserted by St. 1957, c. 765, § 1) which Donahue cites in his brief. No objection was taken to the instruction, and we treat § 2-314 as the applicable section.
