Tyre pressure

Hi

Just wondered if anyone can help me with a question about tyre pressure.

I recently changed my wheels and now have tyres sized 205/75/R15 instead of the original 205/70/R15. This might be a really stupid question, but do I still use the tyre pressure that appears on the label inside the driver's door, or do the new tyres need a new pressure?

I would use the same to start with and see how the ride is and adjust accordingly.

It's such a small difference so stick to standard pressures.
I would get your speedo checked against a satnav just to see how much it has been affected though ;)

I started off high and worked my way down ever since :-)

Speedo will still be running a bit low compared to satnav at 205/75s.
Ihave 215/75s and the speedo is now spot on with my satnav, and calibrated laser speed camera as used by local community speedwatch (dont ask, I just know, OK?)
Stick to same pressures unless tyre manufacturers say different. I have found best ride on BFG ATs is about 24 all round, but depends on suspension set up too

That's why I recommended checking the speedo as your tyres are now about an inch larger in diameter so will affect the speedo and bring it nearer actual speed indicated.
Most speedos under read by about 2 mph and the change of tyre will take about 1 mph off of that so your margin of error going through a camera at say 50mph will be reduced.

For road-only use some people put a bit more air in (say 2-3 psi extra front and back) as this can improve economy without significantly affecting ride or ultimate grip. On most cars it increases cornering power too, but this isn't something you really want on a Jimny...you'd prefer a drift to a rollover :side:
