Morris Minor Owners Club

Hello All,

I’ve had a query from one of the Isle of Wight members regarding tracking. This member has changed from Crossplies to 145 Bridgestone radials on his split screen, but now complains of the steering being really heavy and the characteristics of the car have changed.

He has the tyres at 26 psi pressure and seems to remember reading that when you changed from Crossplies to Radials you also needed to adjust the tracking.

Anyone had any similar experiences?

No - 1/16" toe in should be fine. The pressures are too low - go up to 28 or even 30. But radials will feel a bit heavier anyway.

I run mine at 32psi.
Ian.

I usually run them at 26, but they don't feel heavy unless they've leaked down to about 15 - must get that inner tube fitted in El's car

From my limited experience, radials give a different steering feel to crossys, but probably because there is a lot more rubber in contact with the tarmac.

I was told to run them at 16 and the outside of the tyres started wearing out. I've found 30 at the front and 28-29 at the back right depending on weight

I run mine at about 26-28 PSI front & rear the same.

Do you find they wear evenly? What tyres are you using? Do you think there'd be any difference between 145's and 155's?

Yep, they wear pretty evenly. Tyres vary really, but mostly Firestone, Michelin or anything I can find with tread on.

Are your wearing at the edges, outer edge only or in the middle?

145s or 155s? Well, really the rims are supposed to house closer to 135s, so the wider you go then the more distorted the tyre will be but I can't see that affecting the wear of the part on the road if your pressures are OK.

I used to run 145's at 30 to 32, but found they wore out in the middle - they were Michelins and Dunlops (long time ago)

I'm with Cam. Anything between 26-28 with the same all round

Hmm, I run at 24. That's on LCV rims though - maybe I'll bump it up and see how it feels
