I was wondering what are the widest tires and the widest wheels you can fit on a 90 gt without other work

It all depends on what offset you have on the rims. The bigger the offset, the wider the rim, therefor meaning a wider tire. I have 17x9 rims, with a 255/40 tire. Many enthusiasts can run upwards of a 265, maybe 275, again depending on width of rim and offset. It gets confusing, choose wisely.

[Chalkie011]

the offset will be 4x 4.25 the stock offset for a fox body

What rims you going to have? What kind of tire are you going with?

i was thinkning something deep dish like 03 cobras and i need probably at least 275 to hook up the car. but i was wondering if 10.5 in rims fit wiht no problems

[noble steed]

I think the 10.50's will fit. On the back only. All the wider I would go on the front is 8.5 or 9. I have 9's on the front and they rub like crazy. Never hurts to get a set and try it out to make sure it fits. Make sure you get rid of those quad shocks if you do run a 10.50 rims.

a 10" wheel 6.5" bs
you will have to roll the fenders & remove the quad shocks

8" is about as big as you can on the front and they probably will rub
