Tires: Up grade tire size, r15 tires, size tires

Question
Yes, I have a 2000 Dodge Durango 2-wheel drive with 235/75 R15 tires on it right now.  I was wondering what the largest size tires that I could put on it without rubbing or lifting or getting new rims would be in P-sizing and in inches.  Also, could I understand how the P-sizing works and what 235/75 R15 converts to?  Thanks so much. - Brett

Answer
Brett,

Unfortunately, there isn't a book I can look up to find what the interferences points are, so I can't give you firm information, except to say that there is usuallu enough room to go up a size.

Try looking at Tire Rack's web site for the Tire Tech area.  They explain sizing very well.
