When do you like to change your tyres?

Both PS4 and PS4s are comfort biased tyres due to the soft sidewalls. Have a look at tyrereviews as he did a big test on all the leading tyres. Not much difference in the top results but everyone keeps raving on about Michelins being the best you can buy and nothing else gets close. Ive had PS4 and certainly won't be buying any more due to how soft the sidewalls are and the horrible squidgy feel feedback they give.

Respectfully disagree- never seen that site before but PS4S is better or equal to PS4 in every category. As I said, the main difference is sidewall construction.

I’m running the Goodyear’s now actually and whilst I do really like them I got them before I went stage one and they’re not quite as good as they were previously. I knew this was to be expected however which is also why I’ve invested in the dogbone insert to combat the wheel hop.

I was debating going PS4 as it may offer a bit more grip but now I’m not sure? Maybe I’m just over thinking the whole thing and I just try to stick them out a bit longer.

PS5 has now replaced PS4 and gets great reviews. Costco were doing them for £300 a set last week with Michelin promo (18’s). The offer will be round again soon.

New rubber will always feel better than old regardless.

disagree all you like but Johnathan Benson is a very highly respected tyre reviewer and if he says they are both more comfort biased then I'm pretty sure they will be. Don't get me wrong I'm not saying they are a bad tyre I just didn't like them. We have a very good choice of tyres at the top end at the minute so something for everyone 👍

Can anyone advise on difference between 225 and 235 for an 8j wheel?

One is 1cm wider than the other.

Can anyone advise on difference between 225 and 235 for an 8j wheel?

As @jv has said, they’ll be different widths. Also, for different width tyres that have the same aspect ratio, the height of the sidewall will be different. e.g. a 225/40 R18 tyre will have a 90mm high sidewall and a 235/40 R18 tyre will have a 94mm high sidewall.

I would go 235 tyres on an 8J wheel and 225 on a 7.5J (although 235 will also go on a 7.5J)

[oryx3dr]

The cost difference is fairly marginal but wasn’t sure on sidewall heights. I’m VWR springs so don’t want any rubbing issues or bad looking fitment but I would like the extra grip that comes with the 235s

The ‘40’ in the tyre size means sidewall is 40% of the width 👍🏻
