I have a 90 GT with 8" wheels and i need a taller tire. How big can i go with out tubing it out? Currently I am running 26x10x15 M/T Slick. Any suggestions. My friend has a set of 29x10.5x15 they look to big and I dont want to use them and let the fender chew them up.

The biggest advised size is a 28 inch. Taller than that and you'll get a lot of interference with the fender.

before just throwing a 29" tire on the car

you need to determine the affect on the performance of the car....
top end rpm ....that tire(29") will change your final drive ratio....

Ok I am looking for 28" tire but do you think a could fit a 10 or should I go for 9" wide tire.

do you mean 10 wide tire or wheel ???

you can a 10.5 tire without much trouble

to put a 10" wheel you have to be dead on with the back spacing
and you will have to "message" the wheel opening...

i had to go with a 6.5 back spacing on my wheels....
