MGF alloys

[Tom Maddock]

What size tyre is recomended to go on MGF alloys on a standard TR7

[Grinnalled]

pretty sure they are as the mgf 205x50x15 or 195x50x15

I take it you want to keep the rolling radius the same front to rear. I have used Toyo R888 195 55 15 on the front and 215 50 15 on the rear.There are various tyre manufacturers websites that have a tyre calculator that allows you to enter your tyre and wheel size and this will tell you the information you require

MGF's have different size tyres front and rear. Can't remember if it's 205 rear and 195 front, or 195 rear and 185 front.

 

Either way, I've run 205's on my TR7 and currently have 225/50R15's on MGF rims on there no probs.

On a standard TR7 it's hard to see the justification for anything wider than 195 . . . . heavy steering at low speeds, the potential to feed in loads far in excess of the steering/suspension/axle original design parameters, and seriously dubious behaviour if at all pushed in wet or slippery conditions - even in the dry, once it starts to let go it's all over, no progressive breakaway.

 

A V8 properly uprated all round is another matter, but even then anything wider than 205 on a 7" rim can be more than challenging in the wet, the V8 Wedge is first cousin to an overpowered go-kart as it is.

 

Cheers,

Alec is right. And remember, it's far less costly to renew rear tires now and then

compared to overhauling/changing out/renewing drive train components...

The 185/70-13 is actually a rather good compromise between grip (in the wet) and the

cost of lighting the rears up...
