What will fit on the back?

If you want to figure it out for yourself, here is the strategy straight from Summit: http://www.summitracing.com/expertad...chQuestion=907

Note that if you remove your wheel lip trim or roll the inner edge of your wheel well a bit, it will make a difference. To go really large requires wider wheels, frame notching, wheel well widening, etc.

FWIW, I have Michelin Pilot Sport 295-30-19 on rear (Corvette 10" wide wheels with spacers). Had frame shaved (by Jack Cotton) and trimmed wheel trim. There is room for 325-30-19's in rear on 11" wheel.

Why?

With that much work, it doesn't "fit". The car has been redone to fit the tire and wheel. Not really the info that people are looking for.

i see there hasn't been a posting to this in awhile but thought people might be interested to know. when i got my t, it had 295/50/R15's on a 10" corvetter rallys. i dont know what the spacing dimensions were, but they did have a 7/16" spacer between the wheel and hub. you can see them on my pics. they look really impressive and people thought it was mini tubbed considering the tires were over a foot wide. i had a few issues with them. the passenger side caught on the outside rubbing the wheel well lip. as scott suggested, i could have rolled the lip and stopped that from happening. they also had a problem being off center. the spacer didnt have a lip for the rim to align to as it does with the rim to the hub. and as with the age of the car and having all original rubber bushings, it allowed the rear to move around and rub the frame slightly. maybe if someone wanted to replace all the bushings and machine a spacer with an alignment lip and also to add air shocks or airbags and rolled the fender lip, then they probably would have been ok. since i plan on driving the car i took them off and went back to the original aluminum wheels

I have tested with my customers cars, here are some of the sizes I have found. It is the frme rail in front of the diff.

15-8 4.5 BS 28 -9 -15 1/4 spacer

15-8 4"bs to close to the wheel well lip.

16-8 4.5 BS 275-50-16, fits with 1/4 spacer

19-9 285-35-19, fits in wheel well but will rub with min diff moveement.

So all of my stuff is 15-8 and use 1/4 spacer.

28-9-15
275-60-15
