tyre pressure

[Captain Answer]

I rang pirelli today and they told that these tyres have never been tested as they are not standard fit on any production car.
they told me that ideally, i should not exceed standard size by over 3 %.
they said 19 s were the biggest i should go for safety, i spoze they are right but the 20 s look fantastic.
They also told me that i was exceeding the load on the tyres and my car was too heavy ...????... but if an a3 is too heavy and these tyres or made for touring cars... what car could they possibly go on ? they had no answer for that,There is no feedback on the tyre at all , no data at all, !!!! ? Mine is a 2.0 TDI a3!
I DONT GET IT AT ALL !

A TDI A3 will be much heavier than a touring car chief, why don't you get some tested tyres on either that or stop trying to rice up your car and slam it on some smaller alloys

I'd have to agree. IMO I can't see 20" wheels looking good.... 19" would look very big on an A3. Your running racing rims on a street car, it's asking for trouble. If you like massive alloys then why not try 19".

It's not about the width of the tyre that determines pressure. The greater the volume of air, the less pressure is required. Bicycle tyres are what 50-60 psi and they feel soft. Tractor tyres support large weights and are typically 8-9 psi due to their massive size.

Paul B - it's odd how the A6 runs 30 psi on 235/45/17. I have the same on my A4 and it's 32 all round. I would have thought the A6 would be heavier!!!

Pleased I read this, I would like alloys but cost prohibits me, I like the look of alloys but need comfort more than anything both the wife and I have damaged spines and bumpy rides are out the window, from what you've said I'll probably buy some 205 60 16 to replace the 195 60 16 that are on it now the 205's are an option on my car, would I be able to drop the PSI by a couple?

Dunno about the A6 running 30 psi being odd, i'll picture it tonight.
