Running a 235 tyre on a 225/45/17 wheel.

[benough]

I'm asking on the assumption a wider tyre gives you a bigger contact area with the road.

I've read that it can be done easily and there is no issues but is there any advantage in doing so?

Cheers

cheaper rubber, 235 is a more common size (eg commo/falcon).
more rubber on the road = more latteral grip.

downsides, more bluge, sidewall flex, possibility of eating corners/edges of tyres.

Last 2 sets I'm run were 235/45/17's on stock denvers (17x7.5) and have been fine. they almost corrected the speedo too but run about 2% less on the odo.

And the 225/45/17 isn't the wheel, its just the size of the rubber thats currently on there. the wheel will be 17x7.5. 235's are best suited to 8" and 8.5" but will work fine otherwise.

So in your experience did you get uneven wear or premature sidewall failure?

Does it affect handling?

Oh I know the wheel isn't the tyre size, I just meant the recommended tyre on it is.

Correct speedo would be nice :smile:

Got 235s on mine and no uneven wear of what I can see.

But you're running 18's yo. Are they 7.5 or 8 inch wheels?

I got told by a tyre shop that they would NOT put 235/45/17 tyres on the standard GT sport wheels. They deemed it illegal and it wouldn't fit, so they would only do 225/45/17 for me.

My question now, will a 7.5" wide wheel support a 235/45/17 easily? or would an 8" wide wheel be better?

you got had.
perfectly legal. (correct me here in need be!) My understanding was it had to be within 2.5% of the rolling diameter?
they make more on 225's so they were taking you for a ride.

An 8" will be better as you wont get as much bulge, and this less moving around, but I've never had a issue with eating a corner out or uneven wear.

I've never had a issue with eating a corner out

I wonder if it tastes like chicken

Yeah i figured that, might buy online from now on. Or go somewhere else which will do what i want.

Thanks for that.

I replaced my standard 225 contis with 235 Khumo KU32s.
They are not the top end for performance, but they are very good.
I was not happy (family mainly) with the ride from the standard golf.
They definitely have a softer side wall and you can feel that when you push it into a corner but the grip is fantastic (after 500Km scrub in).
The 235s did not appear to bulge but you could notice the height difference.
At $170 per corner they were great value but if you want to track the car or push it to max on the street then stick to the 225s and go the F1s as everyone says they are the best.

235/45/17 in KU36 would be cheap for daily/light track work, which is what i have in mind.

I would prefer a 7.5 or 8" wide wheel to mount them on, for less buldge (if there is any though?)
