what is the widest 18" wheel i can use on my 84 z28? as well as the best tire size? i would like low profiles.

PLEASE use the feature!

I SWEAR....NEWBIES never use the feature anymore....There are other people asking this EXACT SAME question....RIGHT NOW! How many times are newbies gonna ask this, when it has been asked AND answered 1001 times....

Sorry.....Just frustrates the HELL out of me, seeing the same old questions asked, week after week after week, when the answers are CLEARLY already on TGO.

you can fit an 18x11 with the proper backspacing and some hammering of the front fenderwell, maybe on the bump stop area as well.
It will have to sit flush with the outside of the car and it will be tight to the bump stop and lower control arms.

But yes, use the search function please, this topic has been covered many many times, most threads will be on 17x11's, but the backspacing and such will be the same.

the largest issue you will run into is finding the proper size tire. after 17" the price goes waaaay up, and a 315/30/18 or a 305/30?/18 are not that common, most common is a 295, and that will fit on a 10 nicely., and the selection is limited. You need something around25.7 to 26" in diameter

a 295/35/18 would be a good choice, on a 10 or 10.5" wheel. It will fit pretty well, and you have a decent selection of tires. 6.5" of back spacing would be a good choice for a 10" wheel.
Do you need that wide of a tire?

ok that helps alot thanks for the info. and for the *** on the first reply im sorry that i interrupted your little tea party. if it pisses you off so much don t reply. and save yourself the embarassment of looking like an *** on the internet im only trying to find the correct answers and i have kids so i don't getr alot of time to use the SEARCH feature. give me a break!!!!!!!!

I'm not embarrassed, not in the least. YOU should be the one embarrassed, by not knowing how to do a simple search.

3 kids of my own...7-17....Don't use your kids an excuse for being lazy. Not only that.....You'll get your answer within a few minutes....

He basically said the same thing too....
"But yes, use the search function please, this topic has been covered many many times, most threads will be on 17x11's, but the backspacing and such will be the same."

But by GIVING you the answer, he has "handicapped" you, by not giving you more impulse to do get the answer yourself.

Besides that.....Can you imagine how much the TGO database size could be reduced by, if the same question wasn't asked 100 times?
