Tyre size advice

Hi guys

Looking for tyre size advice -

For a set of 313s, would it be better to fit...

225/35/19 + 255/30/19

Or

235/35/19 + 265/30/19

Are there any differences to handling/performance/economy between them?

Thanks in advance

235/35/19 + 265/30/19 would be my choice.

the top sizes youve listed is the correct OEM sizes but having had them on my previous 320d E92- the ride is nothing short of horrific, the side walls are so thin there is hardly any give whatsover over bumps & pot holes. the 235/265 are much more comfortable & forgiving and no noticeable performance loss or economy.

Would a 235/35/19 be anymore likely to cause wheels to crack due to the lower sidewall height?

Proper tyres instead of RFTs will have a more significant impact to reduce the chances of cracked wheels than an extra 10mm of tyre width.

Avoid RFTs and you should be good.

Thanks mate - I'm looking at going for non RFT, just wasn't sure which of the 2 sizes would be best

A 235/35 is LESS likely to cause a crack as it's a chunkier sidewalk... & RFT IS the main source of cracked rims anyway.

I thought 235/35 would've had a smaller sidewall?

how did you come to that conclusion?

225mm at 35 percent sidewall = 78.75mm

235mm wide at 35 percent sidwall = 82.25mm
