Tyre sizes - I'm confused

[TT Tim]

Hi All,

I know this has been done to death but I'm confused.

Can someone please confirm standard tyre sizes for a RL 17" shod Cerb'.

I think it's:

245/45/R17 <--Rear
225/45/R17 <--Front

Is that right?

Okay, so my next question. what's the largest tyre width that will fit without fouling the wheel arch?

If we're looking at 245/45/17 that matches, in rolling radius, 275/40/17. So, is that an option or is that too wide?

I'm looking at R888 or my favored, Dunlop DZ02G or the replacement: DZ03G as I can spec hardness and they're list 1B. But Toyo don't offer the R888 in 245/45/17.

Any suggestions welcome.

Tim

255/40 rear, 235/40 front on RL7s, both are R888 sizes.

This is a good guide Tim, but you'll need to know the width of the RL rims.

If it helps the 01 owners book mentions

4.2 Front 225/45/16 rear 245/45/16
4.5 Front 235/40/17 rear 255/40/17
4.0 Front 225/50/16 rear 225/50/16

Strangely, no mention of the 18" wheels that came with the car
