Re: Radial tyre size

If u jack the car up at the frame or bumper will that allow the axle to drop enuf to install the wheel without inflation/deflation????

The problem with tire sizing is that they vary among manufacturers by as much 3/4 inch but usually at least 3/8 inch on diameter and width. Usualy the "cheaper name" tires will be slightly smaller than premium name.

Your best bet is to take an existing tire that u like and match it side-by-side to tires in question. HOWEVER if u mount and inflate the tire it will tend to grow in size overall by about 1/4 inch.

The 'cheaper grade' tires are usualy manaufactured by a brand name company. e.g. my Cornnells are made by Dayton tire and i've had other off brands by BF GoodRich, Fisk et-al.
