Default mud tire help

hi,
I will be setting up a nice lift for my winter setup this year on the gc.

Does anyone who's done it already have any recommendations for good mud tires once I slap on some foz struts? I'm looking for pretty much the biggest mud tires I can get into the fender with little to no mods to wells. Will prob go with a 15" rally wheel or even steelies and am looking for all tire.

I see some nice bf goodrichs, michelins, and even some firestones. Do you think I'll be able to get them to fit?

Problem is finding mud specific tires made that small.

Swamped discontinued their TSL in 27" which was the smallest tire they made.

I have 225/70/15 grabber's on my braids but they required a 5mm spacer in the rear to prevent rubbing on the strut.

215/75/15's are fairly common with foz lifts.

Excellent info for what I was looking for. Should be fun once it's all on.

Found a local set already I may take. Thanks!

If you haven't bought tires yet, how about the General Grabber AT2. 215/65/16 is the smallest they come. But they are apparently very capable. and rather cheap new

I was looking at the tire rack and that one specifically... It looks like the dia of the bottom of teh well is ~30" so I may possibly be able to fit a bit larger. And there are tons more sizes. Might have to space a little width and I think I'm going 15" steelies just to get as much tire in there as possible. If fender mods are necessare so be it.

these are what I was looking at...

http://www.tirerack.com/tires/tires....RAT2&tab=Specs

not bad at all in price actually. 110/per


255/70/15
total diam 29.1"
width 10x2" 8.6"tread

hmmm

You will not fit that. Period. ~28" is the cap.

You will hit the spring perch of even forrester suspension. And fender mods are a given.

255/70 is toooo wide. Didn't you read my post? 225/70 required a 5mm. You are wanting to add 30mm (15mm on the inside) of tire on top of that.

Well I am not opposed to flares but obviously I'd rather a better fit than make it fit.

Do you think I can get 215/75/15's in there with a little help or do you strongly recommend staying with 225/70/15. Sorry if these are noob questions, never gone a/t before.

I would rather lower and wider if I can, than taller and thinner. Working on getting steelies this weekend, and have a shop ready to do the work.

A question you may answer? Seems I can max fit 225/70/15 with 5mm spacers as stated but with a little fender cutting...

Wheel wells measure about "30 at the bottom and max 28 is fairly restrictive.

Picking up steelies on sat, then powdercoat then tires then install.

75 on bf goodrich km2s says overall diameter 27.9 so I think I might go for it and see what happens. 215/75/15 hopefully we wont have to cut anything.

I rather 225's but I can only seem to find grabber at2s in 225/70/15. There is a local used set 235/75/15 but I think that's pushing it.

Thanks sc00by luke and scotty for your advice. I think I'll try the 215/75/15 bf goodrich km2's overall diam 27.9". They will be ordered from tirerack. Do nasioc members get any sort of discount?

If they don't work I'll probably sell them and go for the 225/70/15 general grabber at2.

Space them out? Shop has a few sets on deck if I'm not mistaken.

So you think 75 is too much sidewall?

sc00by says he's able to run 225/70/15's with 5mm spacer... but the only problem is grabber is all I can find with good a/t mud tires in that size. Goodrich has a bunch of nice ones but they're 215/75/15 are you more worried about the fenders or strut rubbing with this size?

Yeah with a 225/70 or 215/75 you should be able to clear the spring perch, but not anything bigger. It's pretty close with my tires now.

Grabbers are awesome, love these so far.

Nice! That's good to hear on General Tire review. I'm going to try the 215/75's bf goodrich km2's, it seems like that might be the limit of meat without doing much fender modding.

I'm excited for this too since I'm on coils now and it's just too bumpy sometimes in the city. I actually liked the spring/strut combo on my wrx better than coils for dd driving but this will be nice to have two separate "summer/winter" setups regardless of what's on in either season.

not sure how much snow you get but considering your calling this your winter setup i'm assuming you get snow...

with that in mind, bfg m/t's suck in the snow. I have used full tread bfg's in that exact size with a welded rear diff and locked center and I was having serious issues. My impreza with open diffs and proper snow tires (general altimax, kumho kw19) is FAR more capable than my wagon with the bfg's. They're noisy and don't handle well on anything except dirt/mud...

a much better choice is an all terrain tire that is snow rated like the bfg a/t's. I don't recall if the grabbers have the snow rating but they are probably very comparable.

you will also rub all over the place with that size in the m/t. a/t tires typically measure a little smaller than m/t.

So are the goodrich's. km2s are 8.7 and 8.9 in light and deep snow respectively... but only 6.9 on ice. The t/a ko's are more like the grabber at2s, but I was looking for a little more meat initially. We don't get too much snow here but I drive up to vt all the time. I know they'll be a bit noisy but they have to be better than my yokohama s drives on coils, hah.

http://www.tirerack.com/tires/tires....rain+T%2FA+KM2

Grabbers are better though 9.0 and 8.9 in light and deep snow.

Heres another thread on RS25 with a GC chassis running a massive tire. see how close everything is to rubbing even with the lift. This should give you some insight into whats involved in running a tire of this size. even a small one. Make note of how close the tire comes to hitting the chassis in these pictures.

You don't want to get any bigger than as small as possible. This guy is running the size of tire i mentioned earlier. 215/65/16 Think small or else you'll regret it.

Thanks actually that really helps. Seems like smaller would be better, and I just pm'ed my shop for how much fenderwork they're comfortable with. If we have to cut or modify that only means ability for wider wheels when I come back down too!
