Daveb99 Posted May 12 Report Share Posted May 12 I’m having a set of PS4S fitted to my 18/19 wheels today. Couple of questions... TPMS valves - what’s the best way to ensure the tyre place doesn’t cause any damage? Also, I’ve noticed the PS4S tyres have red dots on them. Should they be aligned to the valve, or opposite? I’m sure I’ve read something about that somewhere.... Quote Link to comment Share on other sites More sharing options...
Solution Bibs Posted May 12 Solution Report Share Posted May 12 Most cars have TPMS nowadays, the garage should be fine as long as you tell them they are there. The red dot is the highest part of the tyre, it should be on the lowest spot of the wheel (they sometimes have a tiny dimple in the rim to show this so less balance weights are needed but again the tyre place should know this, it's what they do after all! If there's a yellow dot, that's the heaviest part of the tyre and should be mounted opposite the valve.

exeterjeep Posted May 12 Report Share Posted May 12 You can remind them about the TPMS, but most tyre places know all about them. Only had 1 place destroy the tpms on one of the wife's jeep wheels, so they just fitted a standard one, had to go back later with a new/correct one. Never went there again, use a good place in Exeter. Quote Link to comment Share on other sites More sharing options...

I have them off the car now ready to take to the tyre fitting place. Quote Link to comment Share on other sites More sharing options...

More often the inside though, depends on the wheel manufacturer.

gregs24 Posted May 12 Report Share Posted May 12 TPMS does require care. Lotus recommend releasing the valve first and letting the TPMS sensor drop into the wheel or it could be damaged as they push the tyre off the rim. Quote Link to comment Share on other sites More sharing options...

Kwik fit have done the tyres on my old NA and my new Sport 410 and never once had an issue with the TPMS. Can't believe they had any special Lotus training. Quote Alcohol. Sex. Tobacco. Drugs.

Daveb99 Posted May 15 Author Report Share Posted May 15 Thanks for the replies on this. Had the PS4S fitted, no issues with the valves, and what a great tyre 👍🏻 Quote Link to comment Share on other sites More sharing options...
Whitey Posted May 16 Report Share Posted May 16 What sizes did you go for Dave, as I didnt think you could get the standard size 18s in the 4S? Quote Link to comment Share on other sites More sharing options...

I was able to get the 4S in 225/40/18 from Blackcircles (and 15% off the rears as well), came to £559 which I thought was excellent for all four. 1 Quote Link to comment Share on other sites More sharing options...
Whitey Posted May 16 Report Share Posted May 16 Cheers Dave, I've got PS4 all round with nearly new fronts but very worn rears - so rather than mix them I'll stick 2 new PS4 tyres on the rear and maybe next time change to 4S all round. Good to know that the 4S is now available in 18 and 19 inch sizes. Quote Link to comment Share on other sites More sharing options...
electro_boy Posted May 17 Report Share Posted May 17 You can also for 10mm wider on the front if 225 is not available. Won't harm the handling at all, thats been backed up by a Lotus engineer. Thats what I have on my car, I swapped over to PS4S last year before 225 was available in 18". Quote Link to comment Share on other sites More sharing options...

I know what I'm getting sorted before my next TDv, after Blyton I decided to have a closer look at what's fitted rather than stopping at "they're P Zeros" its got Nero's on one end and Rosso's on the other ... Not sure what the difference is but I'll swap for 4 PS4S's now the 18" size is becoming available Quote Link to comment Share on other sites More sharing options...
Gold FFM Cdm2018 Posted May 17 Gold FFM Report Share Posted May 17 I had gone with PS4 in the front and PS4s in the rears as they were only sizes available at time late last year. I can’t tell the difference and certainly made an improvement over the P zeros 1 Quote Link to comment Share on other sites More sharing options...
