Hi all,

Any recommendations on Tyre pressures for the General? He's on 275/60/15 and 235/60/15 BFG's

I currently have 265/60/14 and 225/60/14, all at 30psi, drives well and feels good. HTH

Still got the sticker on my door post it says 24 or 26 max
Having said that I stick 30 in all around

I never put less than 30 in anything.

I put 32 in the Challenger for around town. 35 for long runs. 40 in the fronts and 10-12 in the rear slicks on the track.

The Neon gets 33 all the time. The Jeep gets 35.

This may be a red herring, but (at least for bike tyres) modern radials seem to run at a much higher pressure - for instance, 25/28 psi (1970's) to 33/38 psi now for a similar size/weight bike. I've never seen this noted anywhere though...

I think you are correct about that.

The car manufacturers still seem to say quite low pressures in their specifications but the tyre companies themselves always seem to say a higher pressure.

I go by feel on the road more than anything.

To much and you`ll the wear the centre tread, to little and both outside edges will go, if your near the correct pressure should they should wear even,

Back tyres are easy, burnout on some white concrete, have a read of the mark. Light in the centre, underinflated, light on the outside or not getting your width of tread down, over inflated.

Except that centrifugal force will make the tyre seem over inflated when it is not. Kevs technique is great for drag slicks but not so great for finding the best pressure on your road car that goes around corners.

Well i had to join in this thread
If the pressure is wrong it can affect your fuel economy...not that we care much about that in these motors

That is why I always put a few pounds more in for a long trip.

I run between 30 -32 all round..currently 30. it seems to handle better that way. When I got it amonth ago it had 28 in the back and 26 in the front..........the handling improved dramatically when I equalised it all.

I'm running 28 up front and 30 rear,anymore in the front and I have 2 1/2 tons of scrap iron sliding into roundabouts They lock presumably because the tread is crowned and contact area is then less.

Hi Guys!!

Thanks for all your input!!! I'll have an experiment and let you know how I get on

sounds like a good excuse for a burnout!
