Going from 19’s to 20’s Tyre pressure.

I’ve got 19’s at the moment and the tyre pressure is set at 39 PSI all round (235/35/19)

I’ve just bought 20’s and I’m either going to fit (235/35/20) or (235/30/20)

I’m just trying to find out what tyre pressure would be best for both options.

Cheers.

Personally, I would just stick with the same pressure to start with and then adjust accordingly to give you the "feel" you want. The other option is contact the tyre manufacturer and ask them what their recommendations are for your car.

Tyre pressure depending also if the tyres are stretched or not, if they are normal fit, you can go from 32 to 40.... also depending the temperature and the load of the car.

They are going to be normal fit. I’ll mess around with the pressures and see what the tyre manufacturer recommends.

Thanks!
