Yet another T6.1 Suspension question!

[Fishinbrine]

After reading loads on here, I see 265/40R20'S are very popular, are these still good with 8.5J wheels? Also, I didn't want to replace the rear tyres just yet, they have only covered 14,000 miles and still very good, can I stagger front and rears keeping my 275/40R20'S on the rear and 265/40R20'S on the front? I get they are a slightly different rolling circumference but is it too much to upset the van?
Thanks again all!

Are you 4mo?

Nope not 4 motion, but is a T32 so need to keep load ratings of course

Is the rating 103+ ?

I would go with 245. 265 on a 8.5J is too big.

Where's @BognorMotors when you need him!

A few of us have 245/45 on the front 8.5's and 275/40's on the rear 10's, almost identical rolling radius that way, on 20's. As you say, make sure the load rating is right!

I have to agree 275's on a 8.5J don't seem right, it's on the spec sheet as 8.5J's but have just been and measured with a tape measure (can't see the markings with wheels on) and they measure as 9.5 inches

You measured between the tyre mounting flanges - not the outside?

 

[Drive Wayne]

My local tyre place (who I don't use any more) managed to mix my wheels when I originally got rid of the ditchfinders that were on after I picked up the van! Easy to do for an untrained eye! My 8.5 marking on inside of the fronts was only visible when the wheels came off and a bit of cleaning ensued!
The 245/45's I have now on the front are more precise and steering is more responsive. 275/40's on the back are fine and the rolling radius is pretty damn identical.

I was going to try and draw or explain but found this picture! Basically measured exactly like this
