Check your tyre pressures! was created by mlines

Our new Jimny drives well, in fact it has been all the way from "Darn Sarf" to Blackpool and also fully laden down to Hamble and the marinas.

However it seemed a bit light on the front end to me, a smidgen of jimny wobble if provoked by the road surface and skittish in a cross wind.

A quick check of the tyre pressures (it was fitted with new tyres just before we bought it) shows it had been inflated to 28 PSI all round, a typical tyre centre trick.

Dropping the fronts to the recommended 23 PSI and topping up the backs to 29 PSI and it drives like a dream (well as much of a dream as a Jimny can manage).

So if you are not happy with the way yours is driving, check the front tyre pressures. They should be at 23 PSI for normal tyres and a tad lower for fat off-road tyres (I run mine at 18-20 PSI)

Nice one, I'll try and remember that tip for my Jim Jam.

Another tip, get a decent pressure gauge, I have & trust no one.

Had 4 tyres fitted to my car by a pro tyre fitter. Nearly killed myself on the motorway when a group of 'Efniks' swerved into the outside lane directly in front of me but 15 mph slower! :blink:

The tyre fitters' gauge must have been faulty, said he'd put 29 psi in all tyres.
After a pants change, I checked them, approx 8 to10 psi in all of them!!!
You couldn't tell by 'kicking' or 'touch' because they are very low profile tyres.

As you can imagine, the language was quite colourful over the phone! :evil:

This is a question I was just going to ask. I have 215 x 15 Saharas. So should I have about 22 front and 28 rears?

hi ian, i think you might find 28 psi in the rear a bit to much. if the tyres have got a stiff carcass (ie if it was an extra load van tyre before) you might find it to be a good ride as low as 20psi or even lower. its just a case of trying different pressures and seeing what suits you. i dont carry pasengers and find having front and rear pressures the same suits me. i currently run my 31"tyres at 17-18 psi any harder and the rides to harsh, got the same size tyres on my pajero and run them at 33 psi

I run 20PSI front and rear with 235/75, they wear perfectly even but the roll resistance is ridiculous :lol:

M6 southbound around Charnock Richard services is a bad spot for wobble, and when towing a heavy trailer its a death trap even with a shogun, towing the jimny on a quality Ifor Williams trailer it snakes badly. The road surface is very deeply rutted from the wagons. :angry:

Have just dropped pressures from 30psi to 20psi, all round. What a difference.
