Wheels

Is anyone running 20 wheels on the rear and 18 fronts
At all? If so, does it affect handling, traction etc?
I imagine the traction would be reduced?
Any comments appreciated

don't know about traction but ride quality would be reduced due to a lack of sidewall in the 20's

The wheel acts like a flywheel at each corner of the car. If you add weight towards the outer diameter of the wheel, the car will not accelerate as fast because the heavier weight has to be accelerated before the car moves. Always amazes me that folks spend $000s on hotting up the engine to go faster...then slow the car down with big, heavy wheels.

I get you there frenchy Im just looking at the
Traction and how the rear behaves. Ive always gone
With same sizing all round but been told the handling
Is slightly better using slightly larger dia wheels?

Geoff Im not too concerned with acceleration as Im an
Old bloke and dont have the reaction skills I once had !!
I understand what youre saying and it seems strange using
20s on the rear and 18 fronts. Id like to understand
Any benefits/hindrance of going larger. 18rims on a 71 seem
To be as large as Id want to go as Ive seen pics of 22 that
Look ridiculous in my opinion.

On what sort of car? Camaro ? I am running 18s and 20s on my Buick. Love the ride. It's on airbags also though

Traction is going to be more related to tire selection and tread compounds than the diameter of the wheel and it will depend somewhat on what you define as traction as a tire designed for going around corners (track tire) will tend to be completely different to one that is designed for going in a straight line (drag slick).

In a similar vein handling will will be mostly determined by suspension setup and shock absorbers rather than tire size. I'd say in very general terms, stiffer means more direct and responsive, while softer can mean greater grip.

I'd suggest that running 20" wheels on an older car is going to be mostly for aesthetic reasons, rather than any improvement in performance.

I'm now running 18's & 20's on my 71 Camaro. I too was concerned about the ride & handling but going from 15's all round I'm very happy and wouldn't contemplate any other combo now. Also I agree with everything Darren mentions above. There are so many other variables when it comes to how the car grips & goes. Name:  fullsizeoutput_7be7.jpeg
