Can someone tell me what would be the best PSI to put in for a BA XR6?

Everyone is telling me something different, right now its like 33 on the back and 34 on the front.

That's really up to you. I'd run 40 but that's because I prefer handling over comfort. What you've got now is good for day-to-day driving. Even 40psi won't wear your tyres out too fast, but I wouldn't run less than 30. Just play with different tyre pressures and see what works best for you.

I want something that will save more petrol :D
lol

especially since my avg. according to the ford tacho is 13.5L/100kms

MrPlow2

In that case, decrease the pressure of your right foot against the accelerator pedal. jk!

That's pretty good! My average in the AU was 16-18L/100km!

Well, you'd want to reduce the rolling resistance so the pressure should be up there around 36 mark, even 38 if you don't mind the slightly harsher ride.

Danstar

my dad reckon 38 at the front 36 at the back?

should i put all the same pressure in every tyre? is that better?

MrPlow2

You can run lower pressure on the back, which will give you more grip in the straight line, but a little less around corners. However, considering you drive an XR6, you're not going to have much grip around corners anyway, if you push it. hehe

However, that'd be a really good performance balance. Give it a go.

Is it better to put the same psi in all the tyres ?

MrPlow2

It's not better or worse - it's up to you, and whatever you find works better for you.
