Tyre pressure on 18 " wheels

[Mr Freefall]

Anyone know the correct tyre pressure for 18" wheels on the Tuscan. It's currently wearing 35 series rubber.

The handbook only states the pressure for 16" Wheels

Cheers

24 psi Rear 22 psi front were the figures given when I had the 18" wheels fitted.

I guess the correct tyre pressure is what feels right. I would start with the handbook pressure of (F)22 psi or 1.51 bar and (R)1.65bar and then take it up a little at a time

.... until they explode! (ok only jokin)

You'll know when it feels just right

I recently ran them at 25 and 28psi front and rear on an Airfield day and found this to be too high, skippy back end! i think i ended up at 25/25 and it felt right

how about correct pressure for toyos....245/40 and 225/40 anyone know

I don't know whether anyone else has experienced this, but I've had a difference of 2-3psi when I've used air pumps at different garages.

Does anyone recommend an accurate way of checking tyre pressure?

Get yourself a good quality digital tyre pressure guage Halfords etc sell them.Garage forcourt pressure indicators are nevr very accurate and the ones on foot pumps & small compressors are just as bad.

Horses for courses I think. I run my SO2s 18" 40 profile tyres at 21 at the front, 23 at the rear, as recommended by Michael Caine. On a track I found adding 5 psi all round 26/28 made for a very acceptable setup.
