Hello!

I have a 1.8TS with 15 inch rims, the tyres are 205/50, anyone know what the pressures should be?

Thanks

Andy

I used to run with 32f and 30r on 15's

I run 30psi front and 25psi rear !!!
I find this stops the back flitting about when you hit a bump at high speed mid corner.
The handbook doesn't give pressures for 205/50/15 tyres on the 1.8, but the same wheels on the V6 and Q4 are:

Reduced load: front 2.5bar back 2.3bar
Full load: front 2.8bar back 2.5bar

Not sure how to convert to psi, but for some reason I think you multiply bar x 14

Not much help

30 psi is about 2.1 bar.

Seem to remeber getting my figures from the handbook?? Wouldnt use the V6 figures as they are for a heavier engine.

Ang on, I'll go look.........

ere we go..........

for 205/50/15 and 205/45/16 tyres they are all the same!!!

1.8, 2.0, V6, Q4 and TD

reduced load (2 people) f2.5(36.26) r2.3(33.36)
full load f2.8(40.61) r2.5(36.26)

Bit surprised about them all being the same, especially as the V6 is 100kg heavier.

You were pretty close with your maths, just worked it out at x14.5

Guys

Thanks for that!!

BTW I found the cheapest place in the world to buy the tyres, it's probably common knowledge but here it is any way.
They are soooo cheap!!

Micheldever tyres 01962 774437 www.micheldever.co.uk

They did the 205/50/15 Vr P6000 for £63 each all in. My battery is also a bit shot and they do them for £25( kwik fit do it for £65!!!)

Thanks

Hi wrinx, my handbook doesn't give the pressures in psi
It doesn't even list 205/50/15 tyres on the 1.8 or 2.0 litre cars.
Maybe they fitted the wider tyres to the newer widebody cars ??? (mine is skinny)
Those tyre pressures are pretty high, 36 and 33psi !!!!

Wow....might give it a go and see if my fuel consumption gets better

Hi Marlon

Mine doesnt give the pressures in Psi either, I used http://www.convert-me.com/en/ to convert the values.

Guess they only printed the 205's for the later handbooks.

Agree, the pressures seem very high!! But running 36psi on the V6 with 16"/45's as thats what the non-alfa garage told when they fitted them! Also the steering is so bloody heavy if I dont with the extra V6 wieght.

Why not use a gauge that is in bars

By the way 1 bar is nearer 14.7 psi.

Must admit I always talk in psi rather than bar.

I usually set mine at 36 front, 33 rear for the 205/55 x 15.

Mine being a super originally had 195/55 x 15 which ran at 2.2bar front 2.0 rear (32 front , 29 rear)

 

[mal]

ran my 97 2.0 (not super)205/50 on 2.5bar front 2.3 rear as it says in handbook for about 10000 miles and tyres wore round central band first (classic sign of overinflation) and car had ride like a brick lorry. Have used 2.2 front and 2.0 rear on latest tyres, handles well and tyres have noe done about 24000 miles and still a few months wear left.Think my handbook figures 0f 2.5/2.3 about 36psi!! must be a mistake - surely these are for V6

 

[shug]

I am new here so bear with me.My 2.0 tspark has 205 50 15s i am told these are right for this car.Also if it,s allowed where do you guys in scotland come from

[Nicholas]

Td 2.5 full load 2.8 fr 2.5 re
(205/50/r15)(205/45/r16)

all space saver pressures are 4.2 bar .
its funny that all cars come with 15" spare even though some have 14" wheels on with a lower profile than the spare which is 70?
sorry no 8 v figures but prob the same .

 

[wrinx]

Well, I'm buggered with 16" wheels then, never thought about this before! What happens if I get a flat???
