I am in need of a little more rubber for the 540. What size tire can I mount on back of my 70 with a 4 3/4 backspace? 275 or 295? I will go with an ET street radial.

Thanks.....Joe

When general knowledge says to use 5.5" backspacing with that width,why would you order 4.75"?

Got it...not a wheel guru.

No problem,JC. Was just wondering if maybe you had a narrower rear under that car. You're going to need all the tire you can get for that thing. :D
