Anyone know where I can find info on recommended tyre pressure?

[Kooper]

Hey all


My friend's just got himself an MG ZT190, pretty nice.

Problem is he doesn't know what pressure the tyres should be.

It's got 225/45 ZR18's all round, tyre make is Bridgestone, not sure what kind, probably RE71s.

I'm thinking around 220kPa to 250kPa?

Anyone out there with more knowledge on this?


Thanks!

if they're the stock tires they should probably say it on the inside of the passenger or driver door, but other than that i'm not sure i bet the bridgestone website would have something on it

Stupid answer, I know, but is it not in the handbook/on the fuel flap?

That was my first guesses too, and of course trying to do the UCP membership status proud I promptly pointed him to the inside of the doors and the filler-cap, but nothing...
He didn't get a handbook either unfortunately.

I've checked on Bridgestone's Euro website as well, couldn't find anything there either. In fact, using vivisimo, I couldn't find a single site with recommended tyre pressures for different size tyres. Strange eh?

As far as street tires go, I've always kept mine inflated between 28 and 30 lbs. But if you want to double check, call your local Bridgestone dealer.

Sounds like good advice. Thanks all

Ask at a local tyre fitters, they will have a brand new, never been opened book filled with them.

I have no doubt the tyre place has never opened the book - they seem to think my Saab's tyres should be at 2.2bar when the hand book states 2.6bar.....

Yep, I share your experience. Doesn't seem to matter if it's a Morris Minor or a Ferrari, the petrol-jockies this side only know one pressure --> 2.2bar

Usually only max pressure is written on tires. The recommended tire pressure is usually different for every vehicle.

Wouldn't the reccomended tire pressure change with conditions aswell? and I thought the Min and Max were written on tires...oh well.

[johnnynumfiv]

Recommended tire pressures are given for when the tires are cold(not driven on) , you should maintain that pressure when the temperature of the air changes.

I heard the only reason they put that on there is just encase you blow one, they can't get sued

In addition the recommened tire pressure is based on the tire size and standard vehicle weight.

The maximum pressure is for when the tire is operating at its maximum rated loaded, when hauling something for example.
