I really dont know that much on the tire and rim sizing but can you guys tell me if these tires,which are 275/40R/-17 fit on either of these rims 17x9.5 and on 17x11.Also is there a bigger width tire that can fit on the 17x11 like a 285 or bigger.

It will fit on 17x9.5 but not sure about 17x11 may be it fit but doesn't looks good.

Yes.....The 275/40/17 will fit on both the 17x9.5 & the 17x11. I know this because when I first got started in the F-Body scene I ran that tire size in the rear on the 17x11's. I had no clue what I getting into so I went to Merchants for advice. Wrong thing to do They told me 275/40/17 was the absolute widest I could go on a 17x11 rim. Not knowing any better I went with that set up. Waste of money in my opinion. Later I purchased 315/35/17's for the 11's which is what you want for the rear

Not only is the 315/35/17 the proper width for that rim, but it is almost exactly the same height as the 274/40/17 that you would be replacing, so you don't have to worry about recalibrating the speedo, or your car haveing a slight rake forward or backward.

I forgot to mention this excellent website that will help you understand tire sizes:

Great thanx for the info.Do the 315's for the 17x11 rims need any special modifications to be done?Also what did you guys use for studs,reason for asking is that a buddy of mine had some 17x11's but he only had like a couple of threads to catch on.I was a little worried about that.I told him how come you dont get any longer studs?Any way Have you folks replaced the stock studs?
