Tire Size foe 17" wheels

[wdills]

Below are the wheels and tires I was planning for my 73 Mach1 build. A few suggested bigger tires. I am all for it, but I want plenty of clearance so there is no chance of rubbing. For the wheel size I picked, what is the widest tire I can run without worry. Car will probably run a stock height or maybe 1 inch lower. I want 1 size on all 4 corners so I can rotate tires front to back since this will be a daily driver.

215/55R17

 17 x 7, 4.25" BS, set of 4

Rule of thumb is the wheel width should be approximately 75% of the tire width.

A 215mm width tire needs a 6" to 6.5" width wheel. Your 7" wide wheels can use 235 to 245mm width tires.

Use the spreadsheet in this thread to play around with tire sizes to find out what wheels fit and what effects they will have on ride height and engine/road speeds:

If you shop by tire size on Tire Rack you can look at individual tire specifications and see what the suggested rim width is, section width, height etc.

gpierce, I like the look of that tire and wheel size on your car. Are you at stock ride height or did you lower it any? The stance is really nice.

If no one else comes back with experience of a larger tire in this size wheel, I guess 225/50R17 is what I will go with.
