Sorry to say that I don't agree because they have cost limitation... Even more, by default all companies make their car on purpose to understeer a little, easier in case of slippage for the average driver.

I am an engineer with design and race experience... There is always room for improvement, trust me! When you design a car for road use, it is different from track use. It always a question of compromise. Also from a handling point of view, most of the time the more rubber the better ( if you have the power for it that is...)

And I agree with Cossie1600, on a track, I would put some more rubber up front for sure! But on the roads, it’s another story. Having wide tires in front would cause my car to swing left and right on roads where trucks have distorted the road with their tires.

Anyways, the point of this discussion was to figure out how wide we can go on stock wheels without any issues.

Seems like so far the answer is:

REAR:

305’s will fit in the back (but not recommended because tires are wider than wheels specs)
295’s Would fit on rims... but no tire has a good enough diameter compare to stock.
285’s Would fit on rims too and better diameter available... but there is not much difference with stock in width.

FRONT:

255's to 275’s will fit in the front (It’s a question of personal choice as long as you find a good diameter.)

Let me know if you disagree with anything
