Perhaps you chaps can spread some light on this?

If you are upgrading from 16” wheels & tyres to 17” should the tyre pressures remain the same or change?

At the moment I think the original tyres were at 32-33 psi, and I’ve kept the new ones at 32.5psi (Toyo Proxes T1-S).

Any thoughts?

Cheers

 

I think a lot depends on personal choice. If you get 10 replies to this thread, you'll probably get 10 different settings .

I run 34 front / 32 rear using 225/40/17 S02 Pole Positions. Have a play around and see what you like. I don't think there is any hard and fast rule as people's driving conditions vary so much.

Cheers
