For the T30, assuming that the wheels are 8.5” front and back, go for the 255/40 all round. Perfect load rating for the T30 and a good overall size for that wheel.Long time lurker, first time poster so go easy…
My van is a ‘17 T30 Kombi 204 DSG 4motion, owned it 9 months and looking to change the cheap tyres that it came with - Doublestar 255/45/20 on 8.5 rims. New tyres will probably be cross climates.
Sounds like my current 255/45 is pretty far out from ideal (speedo does appear to have been aligned in VCDS though) so have narrowed my options down to 255/40 or 265/40.
So two questions:
- Appreciate this is subjective but will the reduction in sidewall (either -7mm or -12mm) reduce comfort significantly? I do have a set of Koni special actives so my ride is decent.
- Can I fit a 265 tyre to a 8.5 rim? I know this isn’t recommended but is it ok?
Be good to get some validation before I drop the best part of £1k!
You won’t get a significant reduction in ride quality, there should been very little difference. Go with tyre pressures around 38-40 psi and all will be good.
