Hi all,

I did a lot of looking before recently buying tires.  I use the car 
for traveling to shows, races, etc.  It is used basically for touring 
and maybe an occasional Solo event.  I wanted to keep the original 
wheels so that limited my options.

The original tires were 175SR13s' which have a diameter of 23.94", 
5.0" tread and a section width of 7.0".

I purchased 195/70HR13s' which have a diameter of 24.10", 6.1"of 
tread, and a section width of 7.9".

As you can see the diameter increases a miniscule amount but the 
tread width on the road is 1.1" greater on EACH tire than before!

The only place I could find "H" rated tires in this size was from 
Maxxis Tires.  They fill the wheel wells very nicely as Mike Denman 
and Steve Spalding can attest (or look in the photo section).  Mark 
Petrinovich has recently purchased the same tires for his.  I don't 
know his satisfaction level, but I am very impressed with the 
handling characteristics and ride of these tires.  The "70" series 
tires have more sidewall than the "60" or "50" series so the ride is 
a little less harsh and more friendly to the suspension components.

Of course this is my personal choice for the planned usage of the 
car.  If the wheels break or wear out I would probably go to 14" wire 
wheels as seen on Steve Spalding's Marcos (see photos).

For all the different tire sizes and an excellent explanation of 
understeer/oversteer causes and solutions, check out 
www.rogerkrausracing.com and look under "technical" sheets.  Lots of 
good stuff.

My 2 cents for today.
