Tyre Pressure for 265/45/20 TOYOTA HILUX VIGO

[nazree360]

I am currently running on 265/45/20 used on a Toyota Vigo and would like to know the best recommended tyre pressure for the above .....only for city use...feedback appreciated

Have a look at your tire pressure sticker, and tell us:

What's the recommended pressure for the OEM tires?

What's the load rating of the OEM tires? (e.g. 107T, 111H, 113S etc)

What's the load rating of the new tires?

Ok take your truck for a drive, your normal driving. Measure temperatures across the tyre. Adjust tyre pressures so the temperatures across the tyre are even as possible. Then decide if you prefer the optimum use of tyre contact patch or a comfier ride. If it is the latter start letting air out your tyres until you feel it is comfy enough.

This is what is on my car but originally car came with the standard tyres and i changed it to a set of 20"s

Noted but is there like a recommended pressure for the size i have .....

OK, 925KG means it's a load index of 105.

The OEM tires have a load index of 104/106 - so the new tires are midway.

That means you can just use the recommended pressures on the sticker above.

Just one thing - your 20" tires are rated for max. 50 PSI cold inflation pressure, but your tire label recommends up to 51 PSI. Do not exceed the tire rating of 50 PSI....

Pickups can use either commercial or car tyres. The OP's recommended pressures apply to light truck or commercial tyres, as shown by the "C" after the size. Commercial tyres are capable of higher load and pressure, compared to car tyres of the size and load index.

The 265/45R20 car tyre will be fine at the same pressure for an empty or lightly loaded truck. Although the 20" tyres have the same load index as the 215/65R 16C tyres, the rears will be close to their limit if the truck was loaded to capacity, hence the 50psi limit.

Would be wise to be careful how much load is on the rear axle if the truck is ever heavily loaded.

[nazree360]

For starters, the max pressure written on the tyres is the max for a given application, your ride is well under that max pressure limit for your application.

Recommended pressures om your original tyres are exactly that, for those tyres, nothing to do with your new set up. High end Vigos have 265 tyres with a 'recommended' pressure of 29 psi all round. If me I would go for that as starters. Unfortunately your loss in sidewall depth will affect comfort as stock 265/70x16 or 265/65x17 have more sidewall depth and flex.

Thanks Trans .....will give it a go with 29 and adjust accordingly cheers mate ...Thanks a MILLION

A 105 load index tire will lose 25KG+ of weight load capacity for every PSI down - be very cautious when lowering pressures.

The only spec that matters in this case is weight load ability. Wheel diameter/width, tire width/aspect are meaningless.

Safety first, right?

[Jitar]

29 psi is pretty low for low profile tyres, sidewall may be vulnerable to damage and the front tyres will probably wear the shoulders from cornering.

I found 32 - 35psi worked OK on a PJS with 275/55R 20 tyres. These are a taller tyres than the OP with a higher load index and less potential axle load than a pickup.

YMMV (literally)

Thata for sure.....

37 -40 psi

I would follow that sticker tho

And maintain it every now and then. Saves tyres

OP....Have talked to a friend in the 'know' and he suggests 33psi all round. Much to do with pot hole stuff in LOS and you 20's being feeerked..

Hey trans will try it out in about an hout and update ......thank you so much transam
