Opinion

Karpinski, Judge.

Plaintiff-appellant and cross-appellee, Jack Colboch, appeals from a jury verdict in favor of defendant-appellee and cross-appellant, Uniroyal Tire Company, Inc. Plaintiff raises two assignments of error questioning (1) the instructions given to the jury, and (2) the granting of a directed verdict for the defense on the issue of a manufacturing defect. On appeal, defendant raises three cross-assignments of error asserting that (1) the trial court erred in not allowing defense of assumption of the risk, (2) plaintiffs expert should not have been permitted to testify, and (3) the trial court erred in excluding evidence of plaintiffs claim against the Patch Rubber Company. For the reasons explained below, we find merit to plaintiffs objections and reverse the judgment of the lower court and remand for further proceedings. The relevant facts follow.

' On September 30, 1988, plaintiff was injured while mounting a tire at work. More specifically, plaintiff was employed as a mechanic at the Howard Westlake Garage in Cleveland, Ohio. Plaintiff, who had over thirty years’ experience mounting tires as a mechanic, testified that he was asked to help a younger mechanic, Paul Kraig, mount a tire on a Chevrolet pickup truck. The tire was a new fifteen-inch Uniroyal Tiger Paw tire. As plaintiff was mounting it, the tire exploded, causing severe injuries to plaintiffs thumb, wrist, and shoulder.

At trial, the parties presented a detailed description of the method plaintiff employed in attempting to mount this tire. Plaintiff first tried to use a tire mounting machine known as the Coats 20/20 machine. After unsuccessful attempts, plaintiff removed the tire from the Coats machine and attempted to mount the tire on the floor, using an O-ring bead seater. An O-ring bead seater is a device manufactured by Michelin for use in mounting tires. Even with this device, plaintiff could still not properly seal the tire onto the rim because the tire continued to leak air. As the plaintiff continued to apply air pressure, the tire exploded.

The parties disagree as to the amount of air pressure in the tire at the time of the explosion. Plaintiff and Paul Kraig, who observed the events, stated that the tire was not inflated over thirty-five p.s.i. Additionally, plaintiffs expert, Dr. Alan Milner, concluded that the tire was not overinflated at the time of the explosion. On the other hand, the defendant’s expert, Donald Ovila, opined that the pressure was over one hundred p.s.i.

Plaintiffs witness, Paul Kraig, was unavailable at trial. By way of a deposition read in open court, he provided the following testimony. He worked for three *452 years as a mechanic at the Westlake Garage where he had changed over one hundred tires. On September 30, 1988, he was mounting four new tires on a truck when he encountered problems mounting the fourth tire and asked the plaintiff to help. Air was leaking out of the tire as fast as it was being put in the tire. He stated that there was no rust on the wheel and that everything was lubricated according to the usual procedure for mounting tires. After unsuccessfully using the Coats machine to mount the tire, Kraig and the defendant turned to an O-ring. An O-ring is a device commonly used to help create a seal when mounting a tire. The O-ring was used on the whitewall side of the tire, which side was on the ground. Plaintiff had used the O-ring on approximately half of the tires that he mounted and never experienced any problems with its use.

At the time of the explosion, Kraig stated that plaintiff applied pressure for fewer than ten seconds. He also stated that the air compressor was at one hundred twenty p.s.i. Kraig noticed air was leaking from the tire as plaintiff was applying the air pressure. Kraig stated that he was not concerned that plaintiff would overinflate the tire because the pressure was applied to the tire over such a short period of time; it was not possible to overinflate the tire so quickly.

Dr. Alan Milner, plaintiffs expert, described a tire bead as follows:

“ * * * a part of the tire that’s in contact with the rim, the part that defines the opening in the tire, if you will, the middle of the donut, if you visualize it like that, and inside that is a steel wire structure that’s made of material that’s very similar to the wires in a piano, high strength steel wires, and it’s the fracture of those wires under very specific circumstances that are at the root cause of the explosion of tires and tire mounted situations such as we’re concerned with here.”

Milner is a metallurgical engineer specializing in failure analysis concerning tire beads, tires, and tire mounting machines. Milner described in detail the process by which a tire is mounted.

Milner stated that the cause of the tire exploding was a failure of the structural part of the tire bead. He stated that it rarely takes less than forty p.s.i. to seat this type of tire but once a tire is seated, it can withstand pressure of over one hundred seventy five p.s.i. Milner disagreed with the defendant’s expert, who claimed that the tire would not explode during mounting, even in a hang-up situation, at less than eighty or one hundred p.s.i. Milner stated that the explosion “was certainly caused by the bottom bead failure” and that the pressure was under forty p.s.i. at the time of the explosion. Milner’s opinion was based on undisputed testimony that the top bead had not seated and that the tire was not projected high off the ground at the time of the explosion. Finally, Milner concluded that the multistrand weftless design, used in the tire in question, was “unreasonably dangerous and defective because of its propensity to fail too frequently in the mounting process.” On redirect Milner stated that if the tire *453 had been designed with a multistrand fifty-mil wire (as opposed to the thirty-seven-mil single strand design used for the tire in question), it would not have exploded under the circumstances of this case.

Dr. William Seitz was the final witness presented by the plaintiff. His videotaped testimony described the injuries plaintiff suffered.

The defendant presented two witnesses, Donald Ovila and Richard Westlake. Ovila, who worked as an engineer in the tire industry since 1958, testified extensively concerning the structure of tires. Testifying about how tires are mounted, he explained that a clip-on chuck and extension air hose are devices used to allow the person inflating the tire to step back away from the tire during inflation. He also noted that tires can be mounted on the ground but that it is not a very good practice because there is nothing to hold down the wheel. Ovila admitted that a hang-up can occur when the tire bead will not seat no matter how much air pressure is applied. Concerning the various designs, Ovila admitted that the single strand bead design is capable of being broken. If a hang-up occurs, the proper procedure is to let the air out and start over. He advised that if the pressure does not exceed forty p.s.i. there will never be a problem. He also stated that none of the bead designs mentioned would prevent a tire from failing during a hang-up situation at pressures above one hundred p.s.i. Furthermore, at that pressure it would not have made any difference if the tire in question had a single strand bead instead of a multistrand bead. He concluded by stating that the multistrand bead used by Uniroyal was not defective.
