I too am going up to a 15" wheel and I have found the Vredestein Comtrac ,a
"C" rated tire in a 205/65r-15 size and this puts you at an indicated 60 mph
but a real 63 mph speed . This is an acceptable deviation for me as well as
a proper load range at 100.00 a tire. Why mess with gearing if you can do it
easier.

Subject: Gearing and 15" Wheels....

> I am in the process of going to 15" wheels, and in looking at the
selection of tires that have the correct load range and are more of a
street/trail tire, say a 215/70R15 look like they have a theoretical
rev/mile of about 751 revs per mile vs about 797 for the 205/70R 14 tires.

I definitely noticed the difference. Its livable, but I'm not going to win
any 1/4 mile acceration contests - steep hills that I used to be able to get
by in 2nd gear, now require a shift into 1st.

If so, what did you do?
