Tyre sizes

[alkwyn]

I realise I have 275/35 on the back wheels, and 245/40 on front.

Should I be concerned about this?

Thanks

Those are the standard sizes for the 20" option. Same tyres as I have on my Startech 20" Monostar IV alloys.

Stefan - what pressure have you got your 20's set to - the dealer set them both to 30psi when they fitted them, but it looks a bit low. Ta. How about you alkwyn?

Funny you should mention that Andy, I've spent time on the forum today trawling for the same info (don't tell the boss!).

Currently mine are set to 36 PSI all round, but a lot of guys running the 20" option on their SRT8's are running 32 PSI all round. I was going to drop mine down to that and see.

Dunlop recommend 32 front and 35/36 rears on their website but that however presumes you have the 245/40's all round.

I've just travelled 55 miles to work with mine set at 32 PSI (2.2 BAR), they seemed fine set at that and once warm EVIC was reading 35 PSI (2.4 BAR).

Dealer suggested 35psi. As I usually do short trips I have been working to this.
