Yoko ATS on current model forester

Hey heathbar.

Do you know if that size tyre fits in the standard boot well. That's the only question I have before I go out and buy myself a set haha. Cheers

my educated guess is not without keeping it aired down a bit... ckeck the stock diameter of your tire/wheel vs this one. this one is said to be 27.6 inches. Hope this helps. I just hosed off mine from some mudding and found a nail sticking 2 inches out of my sidewall...:shake:
 
According to https://www.rimsntires.com/specs.jsp

225-60-17 has a diameter of 702 mm (27.6'').

215-70-16 has a diameter of 708 mm (27.9'').

So the difference is minimal. You can also do what others have done & "massage" the spare tyre well with a mallet or a hammer & a block of wood :biggrin:

Heathbar, that is a bugger bout your tyre but should be a cheap n easy fix...

On 16" rims though the tires would spread more if they are for offroad use, 17" would be very average offroad even with an AT tyre on. 15-16 inch would be the way to go. Plus you can gain more clearance and less chance of damaging a 17.
 
yokohama back order stinks...

would have been cheap if it wasn't in the sidewall. My tire was worn to 11/32 down from original 14/32... so I couldn't just get one or two due to the dia differences. Plus, they were on national back order here and still are. I plan to get one and have it shaved down to match the other 3 and reinstall, as I am now on 235/60/17 bfg long trails and they rub a bit on the front of the rear wells when the suspension is unweighted
(over big dips and big off camber drops) but they do look cool and are fine going down the highway.

Heathbar: Would love to see some pictures of those BFG Long Trails on your Subie!
 
Sorry to dig up an old thread. I'm thinking of getting a set of at-s sent over from tirerack.com. They're about $150 each so still less than half the price you'd get them in Aus.

As with the OP, my MY10 Forester has standard Geolandar 225/55R17s but the AT-S comes in 225/60R17. That would make the diameter increase about 22.5mm which is slightly more than the 15mm allowed by law in Qld. On the other hand I could go with 215/60R17 which would only alter the diameter by 10mm and (I presume) keep me legal and insured.

Any idea what difference that 10mm off the width of the tyre is likely to make on or off road? Is it purely a visual thing with the car looking slightly taller and skinnier? If not, will the better tread and slightly higher ride outweigh the reduced width of the tyre? Will on road performance be compromised? I'm no speed demon but I like to throw the car around a roundabout now and then. Or as Taza suggests below, is it a waste of time trying to improve the tyres on a 17" rim. Should I just stick with my stock Geos or get a set of Coopers as I'm unlikely to change my rims to 16" or having a spare set just for off road use?

The 10mm lost won't make much if any noticable difference in grip onroad. Maybe very slightly.

215/60R17 would be alright as you have some sidewall. What kind of driving are you planning on doing offroad?

If it's beach and sand 16" rims and 215/60R16 or 215/65R16 would be your best bet.

The AT-S are very good and worth the money. In any condition they will be better than your highway tyres offroad. Proably better onroad too than the stock geo squeelers.
 
I'm looking to get a set of Yoko Geo AT-S in the next 4-weeks or so. If there are any Sydneysiders considering the same thing, let me know and we can do a group buy and potentially save some $$$.
 
Thanks for that Taza. I mainly hit the beach with some mud (or dirt depending on how much sun or rain we've had) in between. I don't have any problems on the beach with my Geos, but then I do tend to steer clear of trouble. Clearance is the main thing that keeps me away from the deep sand ie the Freshwater track up near Rainbow Beach. It's the mud that's the issue for me. The Geos just don't shed the stuff. There's a lot of clay in the mud and once the tread has filled up with the stuff I'm effectively driving on slicks. That said, I've been reading through a few threads on off road driving and I think I need to start switching off the VDC when I leave the bitumen, but that's going off topic.

As much as the idea of having a spare set of 16" appeals, or swapping my 17s for 16s it's not going to happen unfortunately.
 
Hey Smokebelch.

Shame you cant go a set of 16s...the 215/65/16 is only 8mm larger, the 225/65/16 is 18mm larger. Technically not legal BUT, a few PSI drop in pressure will reduce the diameter and make it legal. Thats on a new tyre, after some tread is worn, you'll be back to the 15mm oversize.

For your 17s, I dont think 10mm less width would be noticeable onroad. The increase in profile will help a little offroad IMO. Not much but it might make the difference...
 
Maybe one day if I find a cheap set of steel rims but then I have to purchase and maintain two sets of tyres. Of course if I have a dedicated set of offroad tyres that only get used every week or two they should last forever. I don't think I'll ever have 16s as my everyday tyre though because that would mean the expense of a nice set of rims. I have a Forester accessories shopping list as long as my arm already!

I presume that the more aggressive tread doesn't increase your on road fuel consumption noticeably does it? I know it's not too aggressive

Maybe a little, others have said it does but I havent noticed. I think keeping your Subie running well and going easy with the right foot has a far bigger impact :iconwink:
 
anyone with 225/60r17 geo ats tyres do they fit in the spare wheel well deflated?
 
I have the stock Geo 225/55r17s. Without measuring I had a quick look in spare wheel well and there seems to be a bit of space around the tyre and a gap between the tyre and the floor panel. Get your tape measure out. They're only around 11mm wider (radius). You might be able to leave them inflated. Or of course go to your friendly tyre man and see if you can chuck one in the boot as a test.

What's the law in NSW regards tyres? Can you go that size?

Don't worry about the boys in blue so much ...

BUT be very afraid of voiding your insurance.

I recently asked my insurer about oversize diameter tyres and they had no problems with that (215x60 16 to 215x65 16), even though it is illegal to fit this size to my car. But as soon as I mentioned over width tyres they told me flatly that it would void my policy (215x60 16 to 225x60 16), even though it is legal to fit this size tyre to my car.

Can you afford to cover to cover the entire cost of your car, AND someone else's (you also void your TPPD clause of your comprehensive insurance policy ... )?

That other car could well be worth $100-400K ...

Think about it!

Yeah, definately get confirmation from your insurer first BEFORE you go changing sizes.

BTW, recently had a great test between Geo AT-s and Cooper Discoverer on identical Foresters on the same patch of steep slippery clay mud.

Although the Geo AT-s were only about 10k KMs old and the Cooper Discoverer were bit worn, the consensus were the Geos won hands down!

AFAIC, there is nothing that even comes close to the Geo AT-s for on/offroad compromise :monkeydance:

From what I'm led to believe, you are allowed +/- 15mm of what's on the tyre placement card that's on the inside of your driver door.
This link might help. Even though it's a little old, I'm fairly sure that the same laws still apply (someone please correct me if I'm wrong though)
