How much PSI in these 31" tyres on 15" RIMs?

[gqpew]

Here is a picture of the tyres I have on my GQImageUploadedByTapatalk1359547157.874438.jpg

I believe they are at 36 PSI at the moment.

Thanks in advance.

Bit hard to tell from a picture but ay a guess I would say around the 40 mark........ Don't you have a gauge?

Don't stroke it, TAP it!!!!.....

What the? How much psi should you run?? I use to run 36 in my 31s but I ran 40 on 35" bighorns. Your best option is to find what best suits you but I'd say between 34to40 I'm talking on road but to be honest the question dosnt make much sense to me but I've had a few good luck at getting the answer your after

They look well on the higher side of the scale go spend 5$ and get a gauge

How do you use you tyres? If you are a tourer try about 4 pound less than the side wall of the tyre states. If you only drive around town, I would look at 40 psi. If you carry a heavy load in the back, I would run mid 40's. But then I would not listen to me. No one else does as I apparently know bugger all.

Trying to decipher the question again but coming unstuck (but that's no new thing ).......... so is the question "how pressure should these tyres be run at?" Or "how much pressure do you think is in this Tyre?"

To tap, or not to tap: Well it's obviously tap because this is the signature hey!!!!!! Duh

You need to be more specific, I'll run 40 psi HWY only.
35 psi around town and down to 16psi off road depending

I run 38psi in my 33" coopers for bitumen, gravel and mud. Might drop the pressure if I get a bit stuck

FanTapstic!

Cheers for the answers. I agree that I should've worded the question much clearer. I needed to find out how much PSI should be in these tyres. I think 36 PSI - 40 PSI sounds reasonable for city driving

I had similar tyres to yours and I found 40 psi is about max as any higher the ride is to hard. My tyres were rated for 50 psi. Now I use 33/12.5r15 and they are rated for 35 psi max so I run them at 30 psi.
