Tyre diameter stagger

[Rumbl3r]

What exactly does making the rear tyre diameter 2mm or 1.5mm larger than the front diameter affect?

It seems to me that as long as the ride height is correct front and rear, that the difference in diameter has no effect. Is it just that it looks better?

I await the blatantly obvious answer that I should have though of

Rear tyres tend to wear quicker than fronts so keeping the rears large to start with balances things out during a race, in a 4wd you Could see improved rotation

assuming your asking on a 2wd pan car...

tire split is pretty useful for tuning steering characteristics.
Larger split - more rear grip, less turn in.
Closer split - more turn in, free rear end.
2 - 3mm of split should be a pretty common number.

its not for tyre wear or cool looks!

Hi Mark

Can you explain why it affects the steering, my brain can't grasp it Is it because there's a diff?

Still doesn't explain why, just that it does!

I'll take their word for it and stick to 1.5mm
