Hi,

You're asking about tires and wheels for a TR6...

use 15 X 7 - standard offset. Panasports are an easy bolt on. The sky's the
limit  on how much you can pay, but other choices would include Revolutions
and Keizer wheels. Expect to pay $200 or so per wheel, a bit less for
Keizers, a bit more for Revs.

Note: used ones show up from time to time, I bought a set of used
Revolutions a year ago.

You didn't say that the tires will be dual purpose. If not (meaning that
you'll have tires just for autox or time-trialing), then the lighter the
better - Kiezers are "really light". Panasport also makes a "light" rim,
this is lighter than some but not as light as the Keizers. Remember,
lighter wheels means less unsprung weight... this is a good thing for AutoX.

Given a choice and an unlimited budget, I'd get the Keizers... but I just
happen to have two sets of American Racing Wheel 4 spokes and a set of
Revolutions... I think they're breeding out in the garage, but I need them
all (really!) because before this year runs out I'll have slicks, DOT
radials and Dirt Stockers mounted...

Which brings us to tires. With a 7 inch rim, you could run 225/55 or 225/45
tire. I mention this because 7 inch rims work really well with this size
tire. Now, if your tires are dual purpose (meaning street/autox), then the
sidewall of these tires would be too small for accurate speedometer
readings. I will point out that they make for really good autox tires...
but that's just because I've had really good luck with mine. I'll also
point out that I have mounted the Hoosiers 225/55 tires on 5.5 inch rims,
and they do fit, although the tire guy had fits getting the bead to seat
and had to use dangerously high air pressure to do so... like more than 75
PSI. But they do fit, despite what the "experts" tell you. Granted, this is
not ideal, but it does work.

I'll also point out that the Hoosier Radial DOT tires are very light
compared to BFG's and Yokos - but I would def. not drive them on the
street. There is very little thickness to the tread area and I imagine thay
would be very easy to puncture... I've used the "road racing" compound
Hoosiers for 3 full seasons of Autox... I must not drive them hard enough,
because there's still tread left on 'em. The autocross compound if very
soft and although they will stick very well, I'll bet they don't last as
long as the road-race compound.

If you need more feedback on tires/wheels, drop me line. This happens to be
an area of interest for me, and I am a somewhat rabid autox'er.

Later,
rml
TR6's
