Tyre Stretch - Impact On Performance?

Recommended Posts

tyres stretching is safe - the stretch is not the issue - its the people who do not run either the right tyres pressures or do not maintain there pressure weekely.

if you run stretch you want a minimum of 35psi in the tyres, more if the car is big and heavy.

People need to realize how hard it is to unseat a tire bead WITH correct tire pressures. You already need a pneumatic machine to unseat tires which are deflated.

As cliche as it sounds, take into account most drift cars use stretched tires and look at all the torture they put into the tires and cars themselves...

Defects in the tire from production is another story. If it was a production problem and it happens to be stretched as well, most people will gun for it and make stretch the scapegoat. Ignorant people, I swear.

not meant to be a rant as this is more about what the tyre manufactures say the tyres will fit width wise but i'm still amased how the tyre stretch is always blamed and not the 20psi in the tyre cos the owner hasn't checked it for a few month.

i think owners handbooks say you should check stock tyres every couple of weeks.

Sorry OT slightly, what are your rims Jorge ?? Looks sweet as mate....

Back on topic.

Just bought some nice 15inch rims, 8J, putting 195/65 winter tyres on them, should be ok with that much stretch shouldnt it ??

TIA

a 195/65 is not a stretch. a 165/50 is a stretch!! lo.

i'll be fine mate.

Jorge - 32psi is below factory figures isn't it?

My loon ran 33/34 front and about 36/38 rear by the book i think (from memory) and they never leaked any air

yup I am indeed a first class nipple..............

I am normally really switched on with such things, but your right, I came to fit those wheels and tyres and the damned things dont clear the Calipers..........gutted, and rubberless..........desperation for legal rubber is making me order some brand new alloys in the morning with tyres.

Anyone want some cool retro 15inch modernlines with really good winter tyres fitted ????

Wish I had seen your post re: fitting before I bought the damned tyres, or indeed wheels.

44psi is rubbish mate, will just strip the centyre of the tyre out and 215 on a 8.5 is only a mild stretch.

i'd go 35 front and 38 rear, car should grip better wet and dry like that.

remember tyre pressure will increase as they get hot as well - i expect yours on a hot day will cross 50psi easily.

my rears, set at 38 cold, will creep 42/43 after a decent motorway run of 100miles plus

Hi,

The law on stretched tyres is the same as for civil partnerships between men.
