245 section tyres - will they fit?
« on: January 22, 2009, 05:00:08 pm »
Alright, I need more grip and I am considering some 17" lightweight alloys for track use and wondered whether or not 245-40-17 tyres would fit okay width-wise.

The radius will be 5mm less than the 225-40-18's but it is the width I'm wondering about. Similarly I believe I would have to have at least 8" alloys for correct tyre width fitment too.

The tyres I'm considering are the Toyo R888's see below.

And this is the calculator I used

Any input welcome :happy2:

Funny you mention road legal track tyres, I was speaking to someone today who runs an old factory Leon Cupra Cup car as a track slag and I asked what tyres he used? He said he's found Dunlop DZ02G to be the best, gets a good 6 trackdays (very hard use, soft compound) out of a set if you rotate them and they stick like the proverbial.

Similar in price to R888s and come in either medium or soft compound for about £140-£160 a tyre - something to consider, as a Leon is not far off our size/weight. I think I'll try a set next time.

Sizing, not entirely sure, sorry.

I've managed to find a tyre width to rim width calculator too.

http://www.alloywheels.com/tyrecalc.asp

245 section tyres should fit on anything between 8" to 9.5" :happy2:

All I need to know now is will the tyre width fit under the arches okay?

Anyone?

You will have a mission making them fit mate but I think it is possible with the correct offset. Also unless you run a lot of camber for the front arches you will rub a lot if you want the car to be low, if its high you probably shouldnt have too much of a problem..

I had 235/40/18 R888's on the S3 and that was with a ET42 wheel, I think with an ET45+ wheel and rolled arches, 2+ degrees negative camber you should have them fit on without too much trouble..

Im trying to get the 265's on but I need 9" rims for that, up to now I have only found a couple of wheels than I can get in the 5x112 with the correct offset.

Send me an email and ill send you an excel document that I have which should help you out with what your doing!

I was thinking about also dropping a size to 17" x 8" alloys.

The new OZ Alleggerita HLT ones look promising at just 6.4kg's each :surprised:

Thanks for the info. I've sent you the e-mail :happy2:

265's does look like a proper wide tyre and I'm sure that where there's a will there's a way :smiley:

So, I looked and they do them in 18"...... DAMN YOOOOUUUUUUUUUUUU!!!!!!

Fantastic sizing, 17x8 or 18X8 5-112 ET48. Not cheap though.  :sad:

Looked at them when I was looking at what wheels to get but they were not going to be available until early March apparently.. Couldn't wait that long. They are stunning  :happy2: :happy2:

Cheers guys.

TD, sorry I wasn't trying to spend your money...honest!! :innocent:

I think I'll try and get my local tyre guys to pop a 245 section tyre on for me to check fitment. :happy2:

Just read all the posts again.  Just a thought Hurdy.  Doesn't your brake set up need a little more room than 17"s or am I having a blonde moment.

No problem, we've been discussing lightweight wheels for a while over on the dark side actually and it's been noted that some OZ wheels are a little weak, fine for driving, but buckle easily with potholes etc. that's why the Superleggeras were withdrawn.

Even at 1kg per wheel heavier, I think I'd still go down the Speedline route and save myself £450+.

How about a leftfield option........

http://www.radius-autotech.com/index.php?option=com_content&task=view&id=68&Itemid=151

On the tyre side, you should be OK.  Although the Toyo 888 is a straight side wall the width of Toyo's is usually less that otherr brands IE a 245 Toyo would probably be the same measuerd width as, say a 235 Goodyear....  HTH  :happy2:

Not quite blonde, but the TAROX's will fit under 17"'s It is just that some won't have clearance to the spokes. The Alleggerita's have a good spoke clearance and should still fit.
