I have just purchased a 91 C2 Cab with the stock cup 92 16" rims on it. the car is needing new tires and I would like to put something a little more beefy on the car. Tire-rack says a 245/45/16 will fit the 8" rims on the rear. but I want to make sure they will fit on the car without any mods.

Also I have seen many post about needing to modify the front steering stops if you are putting 225 on the front. what is the Max size that will fit on the front stock rim that would not require any mods to the car?

thanks for your help to a newbee

Hi John,

I understood that the 225 will fit on the front wheels, but I suspect the tires will look a bit like balloons; already the 205 looked like a balloon if you'd ask me. The front rims are only 6" wide. On the rear it will be less like a balloon, as the rims are 8" wide.

If you're looking for something more beefy, you may also consider moving to the 17" rims, which will give you 205/50 front, and 255/40 rear as original 17" sizes. But I guess you're just looking for new tires.

On the 16" rims, I'd stay with the original sizes.

Thanks, I plan on upgrading to the 17's eventually when $$ permit for the Rims. But for now just looking to upgrade the size of the rears.

John,

I can confirm that a 225/50 will fit on a factory 16 x 6 rim, and I can also confirm that they do appear to bulge a bit.

These are my track day tires (Kumho Victorracers) and they work well.

For the record, I also run 17 x 7.5 and 17 x 9 on the street (205's on the front).

There is a small amount of rubbing in the right hand side wheel well (on the inside), at maximum steering lock. Strangely, there is no problem on the left.

I have not determined if it is from the track or road tires, or both. Given that the factory reccomends the steering stops modification when going to 17 inch wheels, I would guess its my road set-up, but I have not tested to find out.

In any event, it is very minor, and I am not worried about it enough to modify the steering stops.

Regards,

Brian

Sounds like I should just stick with the 205's for the front. Any info on putting 245/45/16's on the rear?

Brian Leduc

That would be my track-day rear set-up (245/45, Kumho Victoracer), and they work perfectly, no rubbing that I have noted. They look sweet too.

You do have to be careful though, since tires do vary from brand to brand; a 245/45 Kumho may not have the exact same measurements as a Pirelli, Michelin, etc.

See photo of said tires below.
