Hi guys,
im after some info on tire size.

Iv just purchased a new set of rims and now i need to choose tyres to go with my rims.

The rim sizes are, 17x9 Front, approximate offset +40/+50 , 17x10 Rear, approximate offset +40/+50.

Im thinking of maybe 235/45/R17 Tyres for the front and 265/40/r17 tyres for the rear.

1.My questions is with this offset on the rims 2.will my guards need to be lipped or rolled?
3.Will this tyre size and rim offset give my car a aggresive stance?
4.Any one have any pics of there car with this combo?
5.Should and could i fit 265 width tyres under the ass of my soarer with this offset?

You'll probably need to roll the fronts at least but assuming they're +40 (which is pretty common) and not +50, they should come up pretty flush with the guards.

Running undersized tires like those (235/265) will definitely help.

Thanks cameron. when the wheels arrive in a few days i should have the exact offset.

I don't know about everyone else, but I'd have a hard time justifying $2000+ every couple of months on road tyres when there are better things to spend the money on.

You go through tyres every couple of months? You must be doing an aweful lot of kms or do a lot of burnouts.
I always go for the best tyres and find they usually do well over 40,000 km if I keep an eye on wear caused by alighnmnet going out. Currently shod with 18" Goodyear Eagle F1 Asymetrics which I like very much.
The rears are 9.5" Enkei PF01s with a 45ish offset wearing 275/35/18. The fronts are 8" on a similar offset wearing 245/40/18s.
9.5" is as wide as I could get in an airbag car with this offset. The rim and tyre sit very close to the airbag. No need to roll guards with this fitting. There's a pic on my profile - though I notice in this pic it seems to be sitting up a bit more in the rear than it normally does. These wheels are very light and have to be imported.

Yeah, even fairly soft tyres should last 20-30,000km's with fairly spirited driving.

"better stuff to spend my money on"? As far as spending money on your car goes, tyres are THE best thing to spend money on.

30,000km's to a set of tyres..? In the soarer..? Really?

If I wanted to drive that slow I'd just get in the corolla.

My soarers strictly a 2AM-on-quiet-back-roads-to-nowhere car these days. It doesn't see the traffic and shopping trolley duties needed to rack up big k's.

As far as small tyres on big wheels are concerned, cost is just one reason. Theres better cornering stability, the ability to run wider track (lower offset wheels)and the asthetics (if your into that kinda thing)

Provided you are within the tyre manufactures specifications you will be ok. I think you will find that you will be needing at least a 245 on the front and 275 on the rear to suit those width rims.

If this was true then why did tyre manufactures make the recent tyre molds for the likes of the AD08 wider so that a 245 tyre was actually slightly wider and able to fit on a wider rim than a 245 normally would.

Seems like a counter response to idiots fitting too narrow tyres to wide rims.

Im running 235 and 265 on +40 +40.

Guards will not need to be lipped but this is just about the limit. In the literal sense of the word these are very close to flush. Meaning sitting even, not half a foot outside the guard with a huge lip and -10 degrees camber.

I only paid $620 all up for my front 235 R45 Kumhos and rear 255 R40 Nankangs, not the best tyres but ok for the price

Track oriented tyres like the Ad08's have reinforced sidewalls that don't respond well to being run undersized. There a completely different kettle of fish to the relatively soft sidewalls found in regular road tyres. That said, I enquired about a set of Neova's for my track rims a couple of months ago with this guy:

http://www.gordonleven.com/motorsport/index.php

And he suggested the 245's for a 9.5 inch rim which would be about as undersized as the 235 I have on my road 9's. Considering his reputation, I'm inclined to take his word for it.

That's about what I spend. The set of Maxxis I got last are terrible, but fun to shred non-the-less.

The "improved stability" line on undersized tyres is pure bullshit on a road car. Flex is required in tyres to maintain the contact patch and assist in absorbing imperfections in the road surface. Eliminate flexibility by stretching the tyre wall and you reduce grip and lateral stability. You like driving on backroads? Get some decent tyres that fit the rims within the manufacturers specifications - anything else looks stupid and is dangerous.

wow, loose the aggro man.

I run undersized tyres (which are still within man. spec) because I prefer the progressive/predictable nature created by restricting the sidewalls lateral movement. This isn't something I read on the internet or heard from some random at the pub, its something I've learned from my own personal experience.

If still you have a problem with way in which I prefer to make my car handle (apparently a pretty common preference), I suggest you get over it. (quietly)

Thanks for the useful info guys.
It would be nice to go 275 all round and have front fibre glass fenders and rear lipped/flared gaurds "me day dreaming".
Will post some pics up when the rims arrive in the post and will use all this useful information to pick a tyre size
Thanks again.

No agro intended other than what you are reading into it. I've no problems with anyone running tyres within spec as you are, its the fools who ignore the specs I have problems with.

I prefer the FAT fitment of my 315/30 265/35 +48 18*10.5/9.5
over the 'phat' stretched look fad. If you want sidewall stiffness, buy tyres with reinforced sidewalls. I did. Why compromise?

The AD08's are a street tyre, whilst it is aimed at better dry performance and a little better temperature range thus it can survive with some track work it is still a street tyre.

The AD08's have a particularly wide tread 245's measured about 10.5" and they fit correctly on 8.5-9.5" rims. Typically a 245 is rated for a 7.5-8.5" rim.

I currently run 215/45 front and 225/45 on the rear on 17x9" all round. Fitment was mint when it was lowered although I'm unsure on the offset. I believe they are either P15 or P30. The front tyres only JUST sit in the guards if that means anything. As you can imagine the 215s are really stretched but don't get me wrong, I'd love to run huge rubber on my soarer :-(
