Hi guys

After some advice what is the recommended or best advised tyres pressures for non RFT

Tyres I am running are

225 x 45x 18 XL 95

255 x 40 x 18 XL 99

I have Nokian WR A4 tyres ready for the winter and not exactly sure what pressures to run.

Any help appreciated

Are the winter tyres you have ready, the same spec as the tyres you are currently running? If so, then try the same pressures, as air pressure carries the weight, not the stiffer RFT sidewalls.

If not the same spec, is there a similar spec referenced on the door shut placard, if so, run as recommended, tweak to suit use.

Remember if you use an XL tyre, you may (according to load rating) need to adjust to a higher pressure to carry the maximum rated axle loads. (XL are load rated at 2.9bar, not 2.5bar as standard tyres).
