Looking for peoples thoughts on tyre pressures for the 4x4, especially those who tend to use the car hard

Im off on my annual little Jaunt across Europe in a few weeks, 7 days 5000 kilometres in the company of some rather quick machinery.

Im running 205/45/17 Toyo Proxies & the car is lowered, tweaked etc etc kicking out about 350 BHP.

Im just wondering out of interest what pressures people would suggest I set the tyres at.

We are doing some Motorway driving but a lot of sweeping roads & there are a lot of Mountain sections, the majority of driving will be in France, Italy & Switzerland (the most car un friendly country in the world) So all fairly hot in July

What are peoples thoughts

not too helpful, but I guess the obvious answer is set the tyres hard for the motorway stages and then lower the pressures ready for the next stage in the twisties.

But I would think that worst performance would be seen if you had too hard a pressure on the twists rather than too soft a pressure on the motorway, so go a little softer than standard pressure.

I've tried a few different settings and settled on a lowish pressure of around 30psi all round set when cold.

I travel to Spain each year towing a boat with my 4x4.

I've found that on the sun baked roads the pressures rise alarmingly :thumbdwn:

My advice to you would be run normal pressures, check & adjust each time you stop for fuel.

ps: I had 20psi more than I started with in my trailor tyres when I checked once before! :eek: :eek: :eek:

Toyo have recomended the following cold pressures for my specific needs

Front 2.54 bar / 35 PSI

Rear 2.3 bar / 33 PSI

I like 33 front 35 rear when cold.

That's what I set mine to and that's what it suggests in the fuel cap, but in some funny unit of measurement.
