Guys.

Apologies to what may seem a simple question. I have just replaced the 20" alloys with 21". Now typically I would look to see what the tyre pressure should be by looking on the drivers door. However these only give me pressures of 19 and 20". Would would be the correct pressure for 21" now?

Cheers

I have 275/45 tyres, my local tyre company said 40psi, but a tyre fitter says 36 would be better, and that's what I use now. 2010 3.6 TDV8 HSE (Gone)

Thanks mate. Will pop out later and change it. I’m currently on 33 front and rear ===========================================

Just a thought, I have a V8 which is heavier than your V6, so possibly 33 at the front would be OK, definately 36 at the rear.

Hopefully TYREFITTER will be along shortly to confirm.

I’m running 47 rears & 40 fronts,I was running 37 rears & 33 fronts but I’m on 295/40r22’s & it was a bit sloppy on cornering at high speeds & that’s the reason I’m now trying them with more air in them,I’m running them at the heavy load pressure that it recommends on the dash when you go into the tyre pressure recommendations.I hope this helps. Andy.

For some strange reason I run 34 front and 37 rear in my RRS1 with 275/45 x 21" wheels/tyres, found it rode and handled just fine for me.

33 front and 36 rear works for me..
