Tyre size help please!

[SteveSmith]

Hi all,

I’m going to need new rear tyres soon and since fitting new wider wheels I’ve wanted to lose some of the stretch!

I’m currently running a 235/35 on the front 9j rim and a 255/35 on the rear 10j rim.

If I went up to a 265 on the rear would you drop down to a 30 profile?

If I went to a 245 front what profile?

Thanks for any advice!

I’m looking at the table below...



Does this mean I should stick with the 235/35 front and go for 275/30 rear?

That's a useful table, looks to me you have a number of options.

Have you tried asking the company you bought the wheels off? Worked for me, I went back to the wheel manufacturer directly as well as the supplier, both were helpful.

I'd say they would be a good bet for the answer your looking for.

I'd stick with the same profile or increased profile if it were me.

When reading into tyres for my 224's I consulted Mr Wilks and he's very knowledgeable on all things wheel related! Would be a good idea to also look into prices. For that 10mm increase at the rear (in terms of width) you're probably looking at in excess of £50 per tyre (Michelin PS4 / SS)!

For my rear I decided to reduce the width and increase the profile. That's only on 18's! If I were upping to 19's then I'd definitely want a bit more cushion (rather than dropping) your screenshot suggests you'll be going from 255/35/19 --> 265/30/19
