Skoda RS replacement tyres - interesting

[CanberravRS]

In what circumstances? Big tyres lead to other issues, high steering rack loads being one, tramlining another. In the end a lot of engineering went into the car for its intended purpose.

Its just a feeling, and the fact that the Superb 4x4 V6 at 1800kgs is running the exact same tires that the 1500kg Octavia VRS is a little concerning to me. I know the tire life on the Octavia was brilliant, but i get the feeling on the front of the Superb V6 im going to be scrubbing the edges pretty hard unless I potter around..
Im not saying they got it wrong but its just a feeling based on previous cars that where adequately shod with enough rubber for the task. The VW R36 with the same weight and driveline get 235/40/18 for what ever reason.. so its all a bit odd to me.

Yellow pre FL VRS wagon in Burwood Hwy Ferntree Gully about 10.20 tonight. Turned right into Dorset Road and went north.

Did you look at the PS3s, I put them on our 6 as a test run for the Skoda, they were a lot cheaper in that size, pretty much half the price for the same tyre. So far so good. The tyre people have really liked them as well.

Look at it from their engineering view, a Superb is not a sports car and was never created to drive fast as the VRS etc were, so accepting it was not designed and engineered to do that then the tyres do the designed job. I know what you mean as the front washes out when it is pushed but I am afraid you have to put up with it as to modify the handling would be pointless, the front is just too heavy. It has the Audi disease of the motor is too far forward, all Audis suffer the same way, they won't turn in and when they do they wash out the front badly. My Superb does it and it has not got the weight across the front your has due to no 4WD. Ultimately 4WD is bad for handling as the tyres are being asked to do an extra task which is transferring power to the road and the more you ask of a tyre the less it works well at going around corners. Today after reading your comment I took it out and had a very fast drive through some roads near home for the first time since I owned it and the understeer and reluctance to turn in are very noticeable but I expected nothing less. Actually I was surprised it handled as well as it did as I thought it would be a real dog but was fairly gentle at the most extreme speeds.

A couple of 40kg sacks of Redimix in the rear of the boot should solve the weight distribution issues then.

Scrubbing where? I've got 235's on the back of my RS at present , no problems. It's just that they at GT radials and I don't like them as the traction control comes on WAY too early now. That's why I'm asking about different brands. The Pirelli's are $186 ea (plus delivery, fitting and balancing).

oh really, for some reason i was under the impression that 235s scrubbed. i must've confused with 245s!!
my bad.

hmm, so there's no probs with fitting 235s on the 7.5" rims then? like "tyre stretching"?

Thought I might post this again as the thread is kinda long.


Approved rim contours for various tyre sizes:

R17
225/45: 7J, 7.5J, 8J, 8.5J

235/45: 7.5J, 8J, 8.5J, 9J


R18
225/40: 7.5J, 8J, 8.5J, 9J

235/40: 8J, 8.5J, 9J, 9.5J


So a 235/40 R18 tyre on a 7.5J rim would not recommended by the tyre/rim manufacturer, but you could probably get the tyre fitter to mount them anyway. You should also expect the tyre/rim warranty (if any) to be null and void.

It wouldn't be stretched at all - quite the opposite in fact. The concern is that the tyre might be too wide in section width, too shallow in section height, and the rim width too narrow for it to fit properly (in extreme cases).

Its just a feeling...

The article is dated June 2010 so I presume they've fixed the issue by now.

Try it and let us know what happens, if you want to load the car I will try it for you at your risk. If it were that simple the designers would have moved the CoG back themselves.

I have Sumitomo HTR ZIII's 225/40/18s fitted to my Octavia 1.8tsi (stage 3 - another story!) I chose them after a lot of research and the good rap on the tirerack site. $250 AUD ea and the quitest performance tyre I have ever had. took a while to bed in properly (200klms)

Very happy with them - If I wanted more dry weather summer performance I would go for Hankooks latest Ventus RS3
