Really 37 or 38 on 18s? Since seeing Tony I've run them at 35psi still, same as when I was on 17s.

I think this is a bit speculative still, one member (cous3?) mentioned he was running 38psi and the handling was better so a few others are now trying it too

31-08-2016, 09:48 AM #14Yeah I thought my handling took a turn for the worst when I went from 17s to 18s, and Keith suggested I try 38psi on those instead of 35. It feels a lot better for me. No harm in experimenting and seeing what feels best for you.

I had it tracked at WIM and Tony said to keep it at 35psi all round... Not sure if I'd notice a 3psi difference TBH. Placebo effect and all that :p

I cant say I find the handling any worse on 18s. I have found the car drinks more fuel recently, but I'm not sure if its down to the slightly wider tyres and '3psi' all round.

31-08-2016, 10:20 AM #16How wide are your wheels, Purvesh ? Mine are 7.5". Also I've got uprated ARBs, so I might be looking at the handling at a different point than on OEM ARBs ?

They are 7" mate with 225 tyres IIRC. Yeah and standard ARBs...

I've been using 37psi all round for the last week or so and have had mixed results........the traction is back but the ride is a lot more fidgety (sp?) and I'm finding the car a bit tail-endy.
Going to try another week and then maybe drop the pressures back to 35psi and see how it feels then - I realise that the change in weather may be playing a part as well.

Any feedback from those who are running the higher tyre pressures?

07-09-2016, 11:18 PM #20I think you just need to experiment and see what works well for you Parthiban. My car is handling great with 38psi, but I've got TTE springs and uprated ARBs, so what works well for me might not be the same for you.
