Title: !6" alloy wheels
Post by: nimrod on March 21, 2018, 08:22
 have some 16" alloys on order, I would like to know the tyre pressures, the rear will be standard 215 so I would have thought 32 for the rear, the front will be 195 I know the pressure will be lower I'm guessing 28, I always like to check the tyre pressures after the garage has fitted them as some time ago I had new tyres fitted and the front slid on a damp round about, I checked the pressures and the fronts were a lot higher than it should have been, I dropped the pressures to 26 and they were fine after that.
Not sure what to do with my original wheels, thought I might keep them for the winter but then it's lack of space to keep them, also the tyres will perish not being used, the wheels and tyres are okay.

IIRC @StuC (https://www.mr2roc.org/forum/index.php?action=profile;u=15683) has 16 inch wheels all around. It may well be that he will pop up to offer sage advice.

Nope StuC is a proper tart and has 17"
Start with stock pressure and go from there.
Even on stock sizes different tyres like different pressures.
Toyo T1R for example always like a few psi more.

What he ^^^ said.

I run 28 front and 34 rear on 40 profile tyres (T1R's)

The rear should be the standard 32 PSI, I will just have a little play with pressures on the front when they arrive and are fitted. the 16" wheels have arrived today, they fitted 195/45 and rears 215/45 is that correct?

I have Yokohama S-Drive 195/45-16 front and 215/40-16 rear with stock offset 16" wheels on 2 Spyders. With stock suspension I run 29psi front and 34 rear.  With stiffer Tein-S springs, I run 28 psi front and the same in the rear.  The Spyder does seem sensitive to front tire pressures and 1 psi does make a difference.
