Tyre Pressures on vRS 225/45/17s

greg2302 · 20-02-2004, 15:36

I know this query has been done to death, as I have searched the forums and got plenty of results, but here goes anyway ....

I have always just used the factory pressures (2.0F 2.2R IIRC) but noticed my 205/50/17 Dunlop Sports on the fronts were wearing more in the middle - indicating pressure too high.

I do drive pretty hard on twisty roads, about 900 miles per week, and I got 12,500 miles from the fronts and 20,000 miles from the rears.

I've changed all four tyres now for 225/45/17 Toyos Proxes T1-S although I've literally just driven back through town from the garage so I can't comment on handling differences.

A lot of the previous threads advised running marginally higher than the factory pressures, some of these threads are quite old, so I wondered how everyone had got on with their new settings.

So to get to the point (eventually) what does everyone recommend for my new tyres (225/45/17 Toyos Proxes T1-S ) ?

Cheers

Try them on the factory pressures or marginally below. See how you get on.

At the risk of sounding completely thick..... Is it just a straight swap from 205/50 to 225/45 on the same wheels?

Is there any insurance consideration i.e. will changing to a different profile invalidate the insurance if you don't tell them?

What are the ride differences - is the 225/45 a harder ride?

Reason I ask is that all 4 of mine are due for replacement and 225/45 are about £25 a tyre cheaper

**mannyo** · 23-02-2004, 13:50

Tyres are straight swap. Slightly more noise but better dry grip.

SkodiRS · 23-02-2004, 14:01

I've found my 225/45/17 Pirelli PZero Rossos are actually queiter than the standard Dunlops.

Better grip...have yet to get any understeer from them....only downside is a slight decrease in mpg due to the stickier compound.

I haven't noticed any difference in ride quality.

I'm using 34 psi all around.

Nigel26 · 23-02-2004, 14:33

Dunlops as standard !? mines running Conti Sport contacts and the cars only done 2700 miles so i'm assuming these are the original boots. Apparently they come up at £215 per tyre for the 205 50/R17's on a mates system (he works for national). So i was hoping i could use something else when the time comes. Does Skoda put different tyres on the vRS' then, i'd have thought they'd have stuck to the same really.

i had wondered about pressures as well though.

Only other thing i worried about was the effect changing the rolling radius of the wheels would have on the speedo and its accuracy !?

SkodiRS · 23-02-2004, 15:09

Moving from 205/50/17 to 225/45/17 has a minimal effect on the speedo .....I think there's a 0.3% error. Check out the tyre bible on the site.....do a search for it.

Got my 225/45/17 Rossos from Micheldever for £112 each.

I think the first lot of RS' came with Conti SP1s, then they came with Dunlops....I guess whatever the best deal Skoda can get for a job lot of tyres.

They must be making an absolute fortune at those prices - you can get Sport contact 2s for £87.30 from mytyres.co.uk

The biggest problem I found with buying online is finding somewhere to fit the tyres. By the time you add in the labour cost and valve/balancing the price comes out close to what they could have supplied you anyway. ordering online is good if you are looking for a rare tyre brand/type though.

KentStu · 23-02-2004, 16:14

Maybe im just lucky but there are quite a lot of independent "proper" (i.e. not tyre places full of idiots) garages around where I live where they will fit them for about £10/£15 a corner fully balanced etc.

greg2302 · 24-02-2004, 07:48

I checked with my insurance company before I put the 225s on, no problem they said. My Toyos were £83.60 each from www.mytyres.net, and my local garage does fitting, valve, balance and disposal for a fiver per corner. Nigel, £215 per corner for Conti Sports does sound outrageous, I'd definitely look elsewhere !

Feed the old and new tyre sizes into the tire size calculator in the link below to see how the speedo reading is affected:

Nigel26 · 24-02-2004, 15:29

lovely. the link helped.

so most of you are changing from 205 50/r17 to 225 45/r17 ?? according to the calculator when your speedo says 70 you'll actually be going 69.3 or something like that... WOW ! lol...

Also what tyres are you lot going for? any recommendations?

i doubt i'll be changing them for a while but on the 19 i used quite a few different makes and like the F1 gsd3's although thought they wore pretty quickly.

i thought proxy t1-s' were good but you dont see many places selling them round here now. Bridgestone so3's are supposed to be good tyres as well but are expensive.

greg2302 · 24-02-2004, 17:57

I recently posted a poll and the Goodyear Eagles and Pirelli P Zeros seemed to be the favourites. Incidentally I've seen Eagles for about £70 so as long as you're not doing big mileage (like me) they could be a winner !

jason · 20-01-2007, 12:59

gotta love the searchy searchy button.
just had a pair of GY eagle f1 gsd3's fitted to my vrs ,couldn't for the life of me remember the tyre prssures,so asked the guy to put 34 psi in and i'll adjust em when i got home.(no need)

£149.60 (pair)from mytyres.co.uk
£10(x2) a corner balanced and fitted
£1(x2) a tyre to get rid of my old ones!

used a local family outfit as they were £5 a corner cheaper than the HI-Q.
and now my spare is 225/45/17

krs_vrs · 22-01-2007, 15:29

on the subject of handling, wouldn't there be more tyre movement with the 225 on a 7 inch rim than with the original 205 - ie a wider tyre on a narrow rim???

jason · 22-01-2007, 17:38

not that i have noticed. my main point for changing was the massive price difference between 205/50/17 and 225/45/17.
