has anyone ever widened the rear rims off the 86 z28 to a wider size? i am looking to widen mine for a wider tire, and if so how wide? and what size tire?

 

not many people would put up money to widen a 16in wheel unless its a 17 or 18" wheel and tire avalability are very slim

you need to look up the avaliable tire size for 16in tire and go from there then you can see how wide you can go on the wheel

 

It's been done by another member here. I believe he had 1.5" added to it. Here I took the time to even look it up for you: https://www.thirdgen.org/forums/whee...y-90-iroc.html

Overall yes it does look different. Going up 1.5" isn't going to make a bunch of difference on the tire selection normally. It just comes back to personal opinion. If you're not attached to your rims it would be easier to just replace them. Jegs has a sell on aftermarket ones now for $90 to $120 each which is very reasonable even on their knock off designs.

 

you got a point there. but the selection for performance tire vs cheap everyday tire it is limited vs larger wheel size thats what i mean by tire selection... but if that doesnt matter then your good to go.. but those are better looking wheels besides the iroc wheels vs the 86 z28 wheels and if your keeping a stock look then its worth it

the price for new tires and cost to widen them shipping etc vs just buying aftermarket wheels used or new your prob going to spen 150 to 200 per wheel to widen and the $ to performance gain is it worth it is another thought

and ive seen that thread and he wanted to go wider but tire selection the wider you go gets slimmer 9 - 9.5 would be safe

which a 255 would be ideal or 275 depending on how much stretch or bulge you like

but its personal preference and it would look good if its done right if your going for the sleeper loook

 

IMO it looks great when its done right. I've seen users that have had them widened to a 10 inch or so.
