Title: Larger Wheels and Low Profile Tyres - Less Grip at lower speeds?
Post by: monk180 on August 10, 2019, 10:37:40 pm

Hi,

I have larger wheels and lower profile tyres, and I think they have less grip at lower speeds ?

For example turning tight on a mini roundabout in the wet, the car will just push out, and if then input more angle quickly it looses grip faster.

Or even on a larger round about especially in the wet will power under steer sooner.

My only thinking is that a lower profile tyre cannot sort of "load up" like a normal tyre in those conditions, then as the mass of the car rolls, will be a smaller grip patch as force is being pinched to the outer edge, without the tyre deflecting and spreading the load.

Maybe I am wrong or mad, but any thoughts please

Thanks

Try here lots of information

slip angle on narrow and wide tyres


In Spain atm can’t seem to copy a hyperlink so you my need to google the above

In short it’s not a clear cut as it seams to be the wide narrow question co-efficient of friction and slip angles plus centre of gravity are just some factors that come into play

Sorry for the short reply beer it calling 🍻
