Going up a tyre profile size advice?

[88micm]

Looking a steer from someone more competent than I am on tyre sizes... I have a BMW M235i with 19" 624m rims and am due 2 rear tyres. I have always run it on Michelin PS4s and have seen there is a blackcircles deal through eBay on at the minute for money off.

My normal rear tyre size is 245/30/19 but they don't have those available in PS4s however they do have 245/35/19 available. Seeing it is on the rear and rubbing on steering lock wouldn't be an issue, would it be possible to run these?

I checked willtheyfit.com and it shows that the ride height would increase 12.25mm and Speedo error of -3.75%...

Anyone else done something similar or is it just not advisable??

I wouldn't do it, you'll likely end up with an ABS warning light as the wheel speed sensors are reporting that the rear wheels are going slower than the front due to the larger diameter. If you changed the fronts too then you could but not something I'd be wanting to do.

Thanks for that, didn't even consider this could be an issue tbh
