I'm looking for some low rolling resistant tires for my 1991 Ford Escort conversion. Stock OEM wheels are R13 and from web surfing I only see R15 and R17 low rolling resistant tires. What should I do? Convert to R15 and try to get some lower profile tires to compensate for the extra diameter or are there some good R13 EV tires out there?

Thanks

start here and dig around:

There are some good ones in the 14" wheel size (I have a set of bridgestone B381s) but yeah 13's are harder to find.

If all else fails go for highest PSI available, and run them there. For example these come in a couple of 13" sizes and can go to 51psi:

Thanks for the help.

I found these R13s that I will try the Kumho eco Solus HM KR22. They have them in R13s and are relatively cheap.

I am using these as well.... seem good, but I did not see much measurable difference from previous tires. But, I didn't have a precise way to measure either.... I now have a 'Cycle Analyst' installed and might re-run a test with a couple sets of tires over a set course. I have three different sets of 13" wheels/tires, and am curious now...
