what is the largest diameter and tallest tire with either a 17 or 18 size wheel that can fit up front?

i know a 275/40/17x9.5 firehawk wheel works...what else will work in a 17 or 18?

 

Tried talking to Tire Rack yet? They are about the cheapest and have the largest variety I know of.

 

car craft did a 92 z28 put 17 x 9.5 with 5.5" backspacing all the way around with 275/40-17 tires. had to grind a litttle off the outer tie rods to clear.

in 18" you could get 18 x 9.5 with 5.5" backspacing and 275/35-18

both are 25.7" tall and yes the firehawk wheels fit with the same 275/40-17 tire but they had 5.25" backspacing. so no grinding on the tie rod.

 

backspacing....how do you calculate that off of a rim?

i take it a 275/40 would be way to close then?

 

to measure backspacing on a rim it is from the mounting flange to the lip of the wheel from the backside. teh 275-40-17 came on the 92 firehawk. it fits but no bigger on hte front. some people put the 315/35-17 on the rear with 17 x 11 rims g oto www.skulte.com and you can see some cars with these sizes on them.

 

thanks for the suggestions....

any idea on what the total height of a 275/40/17 is compared to the same in an 18? what about the same but in 35 series?

 

i posted that above.

245/50-16 25.7" tall
275/40-17 25.7" tall
275/35-18 25.6" tall

 

you did didn't you.........sorry, haven't been sleeping much.

how tall would a 275/40/18 be?

what is the largest diameter one could get away with you think?

 

the ones posted are the ones that will work on the car. a 275/40-18 are 26.7" tall which just happens to come on the current corvettes for the rear. and will not work on the front of the car. but the rear yes. i almost bought a set of ZO6 wheels and tires. for my car.

 

so please forgive my ignorance but your certain of this....?

what your telling me is that i can't run a 40 series 275 or even a 265 tire on an 18" rim in the front?


just be absolutely clear.....thanks for the replies....!

 

245/50-16 25.7" tall
275/40-17 25.7" tall
275/35-18 25.6" tall

these sizes you can run all the way around. these are the maximum width and height. the 275/40-18 you asked about you cannot run on the front. too tall.

 

so i guess it's the 275/40/17's or 275/35/18 for the fronts...


what about the rear...running a 295 tire? in both 17 and 18?

 

for the rear you can run a 315/35-17 or 295/35-18

 

i see..............thanks alot!!

 

anytime
