[Fot] Tires

[hakhutch at roadrunner.com]

I am running 205/60R13 BFG T/A tires on stock TR8 alloy wheels on my
TR7 FHC. I believe they are 5.5" width rims. I am having no issues
with this set up. Driven spiritedly and occasionally autocrossed.
While it is not a Europa, I have no rubbing issues on lowered springs
with this extra tire width. 
Perhaps someone can verify the rim width on the TR8 factory alloy
wheels? I do think they are 5.5".Tim HutchisenNorway, ME

 While not specifically a triumph question, I hope I get get some info
here.  I have a ‘73 Lotus Europa John Player Special. The car only
weighs about 1500 pounds.

 The tires that came on the car are:

 175/70-R13 Front
 185/70-R13 Rear

 Because of the weight, the specified air pressure is only 20 pounds.

 The rims are 5.5” wide

 It is difficult to find street legal performance tires for 13”
wheels.

 Some manufacturers sell the 175’s & some sell the 185’s but few
sell both, & those that do, may only sell both using different model
tires. I hate to mix 2 different tire models on the same car.

 If I go with a 205/60-R13, I get basically the same
diameter/circumference as both the 175 & 185 tires, & there are a
number of track performance tires, & even the old BF Goodrich Radial
T/As available. The 205’s would look great!

 From some old on line posts, it sounds like the 205/60’s will work
fine on the rear, with some very slight interference on the front at
full turn lock. That would be easy to deal with.

 Some charts I have seen say that a 5.5” wide rim will take up to a
205, but some say only up to 195 widths are acceptable.

 Your thoughts?
