Tyre Overheating

[Saxon66]

We've had no real problems with the TyrePal and as has been mentioned, it gives a certain amount of piece of mind.

My concern is with the vast difference between the advice offered on line and the 'official' advice from Continental themselves. 20psi difference on the front is quite a bit.

Continental make the tyres, so they should know, and the pressures they recommend for ours (4Season) appear to proving good even though I initially thought they were a bit soft looking. I’ve always thought tyre safe was only any good as a starting point if you couldn’t get more accurate advice for specific tyres.
One problem is that we’re all more used to lower profile tyres nowadays which don’t splay out as much.

It's interesting that from the feedback to this post and many others I've read over the past couple of years, it appears that many people are driving on tyres that are way too inflated. I'll stick to the manufacturer advice and if they pop I'll at least have some comeback ?

No way can the heat from brakes get to the tyre. Don't forget the tyre is in a 60 MPH wind all day.

How come last year coming down the Alps, having to use the brakes, all the tyres were shown overheating from brake temps with the alarms going off?

Sorry but I have to disagree. When I was motorway patrol lorry fires started by tyres catching alight from overheated binding brakes or wheel bearings was an almost weekly occurrence. The hub may only have been smoking whilst the vehicle was moving, but as soon as the driver noticed and pulled onto the hardshoulder it ignited the tyre and often spread to the rest of the trailer within minutes.

Had Tyrepal fitted for a few years now with probably 35,000+ miles. Took a bit of experimenting before I got the warning levels right and it still occasionally shows over-pressure when we're fully loaded, are getting a move on and it's a warm sunny day. I got the cold pressures from Continental and use them as a baseline although the pressure readings are often surprisingly higher. However the ride is fine and the wear pattern is consistent with correctly inflated tyres even if they do look a bit soft. If the alarm does go off we check the temps but they are always in the normal range.

Apart from changing the batteries every 18 months when the readings start to be erratic, which is a simple enough job, we've not had any problems.

Finally a comment about heat transferring from overheating brakes - we've had that happen a couple of times on long steep descents. Just another advantage of Tyrepal IMO.

Ditto here. I posted about this a few months back as a positive side benefit from having a good TPMS unit. Over the Simplon in May and tyre temps crept up as we descended and i obviously was over braking rather than being on the "motorbremse"

Since learnt to manage the foot braking and balance that with engine breaking and done the same root several times and with no issues on the tyre temp, also keeping a close eye on the TPMS temps.

Tyrepal saved my front end. First time out after fitting them and the front N/s went into alarm. pulled into a Garage forecourt, and went to check, The tyre was extremely hot but the wheel was almost glowing (exaggeration) from a sticking caliper. Got some "copper-eze" from the garage and 20 min work with a lump hammer tap tapping and feeding small amounts of C-Eeze into the slider while SWMBO worked the brake pedal, we got under way again, after about an hour with no futher trouble. When I got home after the weekend, I had the wheels and Calipers off and cleaned up Both sides. Without the Tyre-pal early warning the first we would have known is (likely) a loss of brakes!.

Sorry lad but that's incorrect. I've had the plastic valve caps melt on a quite a number of race cars I look after trackside. Some of the claasic cars cars that arent allowed to be modified for brake cooling ducts we had to hide infrared temperature sensors in the wings so we could monitor the tyre temps better so the driver could modulate his style so the tyres didn't go off.
I've also personally had a remould prematurly expire on the M6 on my off roader coming back from a competition. Was only doing 60 but the tyre delaminated... cause... dragging brake I never spotted before leaving!
