Will 17inch rims fit on a 74.
If so what size tire would I use?
Thanks,
Schoon

 

I'm running 8.5"X15" wheels w/ 0.5" negative offset (~4" backspacing) w/ 255/60 tires with no rubbing. Did have to trim a smidge (slightly more than a RCH) off the lower edge off the 'glass behind the front of the rocker trim. So if you get a 17" wheel/tire combo and stay within those parameters, I don't think you'd have any problems.

 

I've had this same question as there is such aslim choice of tires now for our rims, and with 17"wheels we'd have a better selection of good tires.
However, I've spoken with quite afew guys around here about "how their car rides w/ the low profile tires. The word is that they get a much more firm ride. I've said before that I don't like to beat my 'Vette to death due to a rough ride from a tire. In fact, I went to a touring-type tireafter the Firestone Indy due to the Indy having such a rough ride.
My opinion, if you don't mind the rougher ride, go for the big rim and the low profile tire. If you go to any of the custom tire shops, you can take your rule w/ you and measure the height of the different 17" tires and find the size that is w/i the hight and width range of your 15s. I did this in the tire store on Barkesdale AFB about three years ago. Michelin has two great rain tires that are 17" and come in a bunch of different width/ height ratios. I personally wouldn't take anyone's word for it, I'd do the measuring myself. Get the tire to not only fit the wheel well, but keep your speedo working accurately.
If indeed you check into what tire compensates w/ the 17" rim, please post it. Thanks.

 

I never thought about the rough ride that comes with low profile tires.
When I go over a rough strech of road with the tires I now have it's like, is the Vet still in one piece.
Vets don't like bumps etc.

I will need to re-think this one.
Thanks for the input!

 

This can give you some idea of what you can fit: http://www.1010tires.com/TireSizeCal...?action=submit

It looked like a 255/50-17 would be almost the same as my 255/60-15.

 

Good info thanks!
