466049 2006-06-25 22:22:00 my sisters car has tubeless steel belted radial tyres.One of these tyres looks like it's nearly flat. Can u inflate these tyre of tyres at the petrol station? what does tubeless steel belted radial tyres mean anyway? What PSI would u inflate them at the petrol station if there's no recommened PSI rating on the tyres of doors? lance4k (4644)
466050 2006-06-25 22:33:00 As do most cars on the road. Any petrol station air pump will do it. Exact pressure depends on type of car and whether it's front or rear tyre. 28-30 psi would do until you get correct details. It's unusual for tyres to go flat by themselves, keep checking it and if it loses pressure again look for a nail. PaulD (232)
466051 2006-06-25 22:35:00 All modern tyres are tubeless. Have been for many years (you can still fit a tube if you need to, under certain circumstances)

Most modern tyres are steel belted radial tyres.

It's just a tyre.

Of course you can inflate the tyre at a service station.

Perhaps if you could mention the make/model of car, as the inflation pressure for a Hummer will be different that a Suzuki Alto.

466052 2006-06-25 22:44:00 it's a honda accord v6 i think.tyres are 17inch.So would it matter if u did inflate the tyre at a lower pressure that it needs, what would that mean? whats the whole PSI thing anyway.most people say use 32PSI and it'll be okay. lance4k (4644)
466053 2006-06-25 23:50:00 if you under or over inflate the tire tread won't sit evenly on the road and it will wear uneven. not to mention you will loose traction as part of the tread isn't doing much.

30ish psi is ok. you can go up or down depending on the way the vechile handles with those tires. some like 32, some 36, some 26. need to work out what it likes best then write that down so you don't forget.

personlly i prefer a little overinflated it generally handles better than under inflated.

466054 2006-06-26 00:28:00 Whatever presure you settle on make sure you check all five tyres on the car.

32 - 36 for the tyres on the road, all the same pressure, or at least same front and same rear.

Spare as above if it is a normal tyre, or 60psi if you have a space saver.

Hondas generally have a helpful sticker by the side of the doors, so look out for them. It'll tell you the exact tyre pressure you need.

Otherwise, read the car manual!

Of course, only if all else fails.

thats not really a good guide . that may suit the factory tires but it certianly not going to suit the 17" low profile tires that car has now . there is no one presure all tires run at, even if they are similar in size etc .

thats what i hated with my car, by the time you worked out what was a good tire and what pressure suited it best the manafacture has stopped making that particular tire and your back to square one ! some people will go hunting for any leftovers around the country because of that .

You are right about the hand book being a bad guide, especially if you have fitted after market wheels and tyres . I have been in the tyre industry for the last 15 years and run/part own a store in my home town .

If the tyre was half flat it was that way for a reason, get it checked out, air doesnt just fall out of the tyre for no reason .

All 17" tyres I fit or check pressures on are set to at least 40psi, they need to be high to work properly . If you run them at a lower pressure(below about 15psi) for long periods the tyre will self destruct, this is were poeple say " it just blew out for no reason!!" what they dont realsie is that each time the tyre goes around it generates heat through friction inside the casing . This heat is transferred to the air inside the tyre which then expands and therefore increases the internal pressure of the tyre putting load on the already "stressed" sidewalls . Blah Blah Blah

Anyway there is more to tyres than just making sure they have tread and dont "look" flat . Like I said earlier if you had to ad air then it has a fault, get it fixed before you stuff it completely
