Tyre pressure

Recommended Posts

Can anyone recommend tyre pressure for 275/55/20 on a 2013 Ford ranger ( won't be hauling much weight ).

TY

I would start with the maximum pressure listed on the sidewall of the tire.

If that ride is too firm for your liking, reduce each tire by 2 PSI and try again.

But certainly more than the 32 PSI that Thais seem to think is the law.

Thanks for the replies, nowhere near the installer and would not really trust what he'd say anyway.

I will check he sidewall and take it from there. Where's the pressure on the tyre, near the sizes?

There is a bunch of small 'print' on the sidewall, it will say "Maximum load xxxxx at xxxxx PSI"

Jesus!!! RTFM!!

Edit: And basically with that low a profile, it doesn't really matter, it will ride like <deleted> anyway. Why people buy a 4-wheel drive and then but bicycle tyres on it has always been rather an amusement. Got a noisy exhaust to go with it by any chance?

I have had various new light trucks over the years, and without fail I always found the pressures stated in the manual to provide too soft/bouncy of a ride, as well as making the handling less firm than I care for.

If you start at maximum pressure as soon as you sit in the car or add more petrol you will be over maximum pressure.

Gsxrnz, I missed that detail...in the case of aftermarket tires the manual means nothing.

And we are in 100% agreement on the low profile tires...you almost have to run them at or near max pressure to keep from bashing your expensive rims on the great roads found in most places. They will definitely give you a shitty ride.

Yep, first pothole (translation: small swimming pool), and you've knackered your rim. And if you suddenly brake to save your rims, you'll be wearing a two scooters and a concrete truck up your jacksie. TIT blink.png

The tires are designed to carry the max weight at max pressure. Putting the tires at max pressure, then adding 80kg of driver is going to increase the tire pressure by a negligible amount.

Also, the max pressure is rated with the tire cold...the manufacturers allow for air expansion aka pressure increase when the tie warms.

This basically shows wot you know - SFA!! The ride is fine with 55 profiles.

I have another vehicle with 40's, now that is a rough ride ( not a truck though ).
