The 15X7" with 205/50 is what I want to run. A 4.75" backspace is an ET40
offset, I believe. Any off the shelf options?
I hate to trim the valence, as the car was just painted and we welded in a
nice reinforcing "lip" on the inside of the piece. I'll have to take a
closer look, as it is entirely possible that the valence has been trimmed
"back
in the day". I can compare with the one of the other Tigers at the shop.
Not too concerned with steering effort, but that is a great point.
My other thought may sound strange, but I'm also considering running 15X6"
all around with 195/50 Toyos. If I did that, I would make a billet spacer
(hub and wheel bore centric) to push the rears out a bit.
Thanks for the info!

I personally like 15 inch wheels with 205/50 tires on 7 inch rims. That
is the setup I have for my "street tire class" autocross tires. They give a
very nice ride in conjunction with my 450 lb. front springs. My regular
street wheels are 16 inch wheels with 7 inch rims with 205/45 tires in the
front and 215/40 tires on the back. The result is a bit on the harsh ride
side.
The issue with 7 inch rims on the front is to have the correct backspace.
You need a backspace of 4.75 inches to get the wheel and tire to fit
reasonably well inside or equal to the outer fender line and still have the
wheel clear the suspension control arms at full deflection. Given the width
of
the 205 tire, you will have to trim off about 1/4 inch of the lower edge
of the front valence where it curves back a bit toward the wheel opening for
clearance at full steering lock. Many people have done that and the
trimming is really not noticeable to any significant degree. I did not have to
do any other wheel well or fender lip modification.
While you are not predisposed to 6 inch rims and narrower tires on the
front, keep in mind wider front tires result in a noticeably heavier steering
effort especially at low speed.

Subject: [Tigers] Thoughts on 7" front wheels
I'm about to buy some new wheels for my Tiger. Because of the lack of
quality off the shelf wheels for our cars, I'm leaning towards 15"
diameter
Panasports. While kind of "belly button" wheels, they are very well made
and
reasonable cost.
The usual 6" front/7" rear fitment has limited appeal, primarily because
of the handling compromises that result. I'd like to run 7' all around
with
equal size tires.
Anyone have direct experience with the 7's and clearances? My valence is
near stock, we did do some basic smoothing, prior to the car going to
paint.
How large a tire might fit? (I could see running as small as 195/50-15 at
all four corners).
Thanks for any thoughts!
Mike Wood
