R line tyre pressure

Post by Zastrola » Thu Mar 14, 2019 9:27 pm

Hi guys,picked up my new RLine 1.5dsg up yesterday just getting my brain frazzled looking through the manuels.
Was wandering what tyre pressures you find the most comfortable, also is it possible to view the actual tyre pressure through the TPS monitors or do you only get a warning if the readings come out of the tolarences?
Thanks in advance.

I have mine at 36 PSI, the monitors only give you a warning and you have to reset them when they have been activated.

The tyre pressures are on a sticker halfway down the "B" pillar of the R-Line stating the different load factors / pressure. When you have adjusted each tyre you reset the tpms and any deflation will trigger an alert.

When I picked mine up from the dealership the ride was rock hard and very uncomfortable, I could literally feel every imperfection in the road surface. I initially put this down to the 19” wheel and low profile tyre combination. After a couple of weeks ownership I decided to check the tyre pressure, each one was reading 46 PSI, that’s 10 PSI over the recommended setting! I dropped the pressure to 35 PSI and reset the TPS monitor. Obviously the result was immediate, the ride was so much smoother and much more pleasurable.
I’m very surprised this wasn’t picked up on the PDI inspection, I think it’s probably wise for new owners to check their tyre pressure just to be on the safe side.

Ah, 19in wheels and low profile tyres - the bad old days for me. I think the psi is set high when you pick up so you don't trip the tyre sensors too soon; once you drop the pressures, you'll find the sensors will trip painfully often.

I would use the lowest psi for your tyres and set the sensors; then I'd add a bit more air as a "buffer".

Sorry but I have to disagree. Set the tyre pressures as per the manual/B-pillar figures and then set the TPMS, there is absolutely no need (IMO) for any “buffer”.

I have to disagree about the sensors tripping often. In 5 years of previous Audi ownership - S3, RS3 and RSQ3, which had 18, 19 and 20” wheels respectively, I only ever had the TPMS trip twice incorrectly- and to the best of my knowledge, VAG group use the same sensors across the range for the type of TPMS fitted to the T-ROC.

Setting a higher pressure than recommended will lead to faster tyre wear, and reduced braking and handling.

As regards sensors tripping, I can only post that which is my experience (in case it chimes with someone else's experience too). I accept that your experience is different.

On my car the tyre pressures can be set at comfort level (or not) i.e. a lower psi (or not) but, my bad, this isn't available on low profile tyres. I got thrown that this is an R line question but not in the R line sub, sorry :oops:

Speaking personally, I don't like the skittishness of big wheels/skinny tyres but each to their own. Our pot-holed roads are not a good place for them either.

I’ve ordered the R line, 19” wheels and agree the larger wheels will create a harder ride on our uk roads than say 17” with taller rubber. I prefer the seats/extras you get with the R line but the downside could be the ride quality. I’ve specced the costly DCC chassis control which I have on my current golf and like the option of comfort setting but also find the sport settings tighten everything up (not technical) and improves ride quality on certain road surfaces in my area.
My experience of the VW tyre pressure monitor is overall pretty good as long as they are working correctly, I’ve had a couple of incorrect warnings and there’s nothing worse than first thing in a morning and you hear the ding of the TPMS and the trip to the garage, it’s the same noise as the outside temp when it warns of ice temp below 4.

I took delivery of an R-Line 1.5 in June 18 and within a week the tyre pressure sensors came on. When checked, all tyres were set at 49 psi. When I spoke to the service manager, he said that it was the standing pressure, (mine was from stock), due to the fact that if they were in the showroom they set them high to stop the tyres getting flat spots, (true or not, I don't know).

Over the next few months my tyre pressure sensors continually came on, (all 4 wheels had the same issue), and whatever the garage did it didn't cure it. To cut a long story short they ordered a new car and I took delivery in November, all tyres set at 35psi, and as yet no tyre pressure monitor indication has come on.

I previously had a Golf mk7 and a Tiguan with the same tyre pressure system. It only ever came on once with the Golf, and that was when I had a puncture..

I agree with what most others have said, apart from T Roo. Sorry :|

I have TPMS on my current Golf and 2 previous Jettas, and have never had any false warnings. The one or two occasions when the warning was triggered were due to low pressure, in one case a cracked alloy due to hitting a pot hole and the other due to lack of checking the pressures for a long period.

I set my pressures mid-way between the lowest load and the medium load setting, which allows a bit of mixed load without keeping adjusting the pressures. I always reset the TPMS after ajusting the pressures and never give it any top-up, which is unnecessary and defeating the purpose.

The TPMS on VW cars compares the rolling circumference of the wheels, so if all tyres wear down at the same rate there is no issue but if you replace one tyre due to a puncture, then it can cause false alerts due to the different tread depth of one tyre compared to all the others. When adjusting the pressures (or changing tyres), it is important to drive for a mile or so before resetting the TPMS so as to allow the system to 'learn' the new rolling circumferences of each wheel. That's my understanding anyway.
