215 40 19 on 8j fronts or 235 35 19 on 8j fronts will both add comfort + protection. Increase accuracy on speedo & reduce arch gapTeeMac wrote: ↑Fri Mar 16, 2018 9:26 amWe might be at cross purposes here - the suggestion was to increase the tyre profile, not the width. Going from 225 35 to 225 40 on the fronts increases the sidewall height by 11mm, which might introduce the risk of fouling, hence my question.HillWalker wrote: ↑Thu Mar 15, 2018 10:28 pm Going from 30 profile to 35 on the rears makes the speedo 2.8 mph slow at 90 mph as smartbear says that probably makes it spot on, and going to 235 fronts only takes the sidewall increase from 3.1 to 3.2 in so no problem with it fouling on anything.
That said 225 35 19 isn't really the problem , it's the rear 30 profile that is
