One of our club members just bought his son a 79' Cobra with the TRX suspension and the Metric 15.35" wheels. He is trying to find a set of tires and going crazy. Originally it is supposed to have 190/65R x 390mm on it now is 220/55R x 390. He said he found one set at $300/tire, any suggestions on where to look? I told him for $1200 I would look for a new set of rims and tires. Are the 88-89 four lug rims the same bolt pattern as the 79-80?

Thanks for the help

Michilen originated the TRX design and it had the same fate as the Edsel.
Dayton and Cooper booth offered 390 MM replacement tires. Try a Discount Tires chain store. They carry many inexpensive "off brands".

The TRX tires are next to non-existant and extremely expensive these days. Any Fox wheel will fit on any Fox car, so there are lots of choices out there. If you're interested, I have a set of 16" Pony rims off of my '93 sitting in my garage that I'm planning on getting rid of.

Do your friend a favor mike and get him to "give" (as you will not be able to sell them unless they are mint and you find that guy who is keeping his pace car totally stock) them away, he is much better off buying a set of ten holes, Turbines, or even better, Ponies.

They will be cheaper to buy both rims and tires then just buying rubber for the TRX rims.

Tire Rack has the 220/55 size available for $207 ea. '79-'82 TRX suspension package cars came with the 190/65R390, and '83-'84 came with 220/55R390.

Unless it's a concours show car, I wouldn't even mess with them. They were crappy tires back then, and would be really bad by todays standards.

I have to agree here. I have a set of the 220/55Rs for my 79 Pace Car, and they could barely keep up with the stock 2-bbl, single exhaust 302. I put on a set of 1990 turbines with BFG 235/60R-15 Radial TAs and the car handles MUCH better.

I put the TRXs back on recently for a picture to go in the Auto Trader (I'm selling the car... see the Classifieds section for the ad), and with the modifications that I have done to the engine/drivetrain, these tires are downright SCARY to drive on. 2nd gear traction is non-existant, and 3rd is a bit squirelly even on clean, dry pavement. Add a bit of rain and I won't even take the car out. I'm running less than 300 hp too. The turbines are going back on this weekend.
