Ditching 326s / RFTs & Need Advice Please

Post by Dazza4 » Mon Feb 27, 2023 11:18 pm

Firstly, I’m really sorry to start a new tyre thread - yep I agree with all of the groans, I’m tired too :headbang: But having read a lot of posts lately, sadly I’m still unclear and as it’s a big investment, I really would appreciate any feedback in layman’s terms.

Currently have original 326 alloys (all need refurbishing) and the following with Potenza RFTs: Fronts 225/35 R19 88Y and Rears 255/30 R19 91Y.

Looking to replace with new Veemann alloys and non Run Flats. Objective: add more comfort to the ride, save my back, have no rubbing/speeedo accuracy issues and enjoy the car even more. All of this is a relatively large outlay, hence this post.

Anyway, thinking of sticking with 19” alloys, and a premium brand tyre (MP4S, Contis) what’s the best option to achieve the above objectives;

1. Stick with the same side/profile etc as above on non RFTs?
2. Go to Fronts 225/40/19 and Rears 255/35/19 non RFTs? Is this one profile up?
3. Or go to Fronts 235/35/19 and Rears 265/30/19 (suggestion by BM Autosport)
————

Or admit I prefer comfort over looks and switch to 18s?

I struggle with all the technical speak, so appreciate any advice. FYI went on that will it fit web site - didn’t help me as out of my depth.

Cheers for any constructive feedback :thumbsup:

In terms of improving comfort worst to best

19” runflats
18” runflats
19” stock sizes MP4S
19” stock sizes SC7
19” stock sizes Assy 5/6
same sequence with 235/35 265/30
same sequence with 225/40 255/35
18” same sequence

FWIW I doubt almost anyone would notice any detrimental effects on handling with 18” vs 19”

Obviously not every Tyre is available in every size…SC7s only really a 19” fitment for example ..

If you are going with new alloys 8.5j and 9.5j give you more options on tyre widths

A 35 can easily overwhelm a lot of tyres…
We choose to go to on with this endeavour at this time and do the other things, not because they are easy, but because they are hard…
