light truck tyres of rallyX?

[acco205]

i know most people suggest snow tyres, but what about a set of LT off road tyres?

seems like they would have less of an issue with debeading and maybe last a little longer since the compound wouldnt be so soft.

anyone have any experience? Sizing is somewhat limited, but 215/60R16 (the smallest ive found) is almost the exact ride height as my street tyres.

Many types of LT-A/T tires work very well and often fall between a good A/S tire and snow tires and true rally tires in terms of performance. They are going to be harder than a snow tire or a rally tire but won't overheat and start chunking like snow tires do in warm climates.

The main issue to consider is classing. Sine I see you're in San Diego, in CA, at a CRS event, depending on the exact sizing/type of the tire, an LT tire would put you in the rally tire classes - be sure to read those rules here: http://www.californiarallyseries.com/Current/Rulebook/index.aspx#rallycross_championship. At an SCCA event, you might be outside the allowable +/- size range (10mm on the width, 5points on the aspect ratio so for example, your stock tires would have to be a 205/55/16) for their stock class as well. If your car is already modded beyond stock or you don't care what class you run, go for it.

it's actually +/- 20mm on the width for SCCA.

205/55/16 is my RSs stock tire size... I'll have to look into these next time I'm in the market for rallycross tires.

I stand corrected.

Stock tires would have to be larger than 195/55/16 or smaller than 235/65/16 for these to be legal.

[Usher]

Actually, for 2011, there is no tire width limitation in SCCA events, except that the tire can't rub.

Here's the updated stock class tire rule for the 2011 season, copied from the Dec 2010 Fastrack:

6.2.C.2 Tires must be DOT approved. Tires marked ‘For competition only’, ‘Not for street use’ or similar, are not allowed. No part of the tire may be modified or altered from its original form, either through addition or subtraction, other than normal wear. No studded tires are permitted unless ice or snow is present. Studded tires may not be homemade using bolts or screws. Only street legal studs are allowed. Tires may not interfere with any parts of the car (fenders, fender liners, suspension, etc).

acco205, now the only thing you need to do is check which events you'll be doing. If they are the Glen Helen events, check with what Jay is going to use for tire rules. As for other events, like the CRS rallyschool and rallycross, you would be classed according to their rules, like MarkA stated earlier. As I suspect though, you want to just get some tires and have fun, right?

My stock wheels are 17s so no matter what I'm out of stock classing (my second set of wheels are 16s), so yeah, pretty much just looking more for screwing around an practicing my driving, but not wanting to invest in something I can't run in an event.

Thanks for the heads up everyone!

Jay is petty committed to SCCA classing. Mike would go CRS, but his venue requests didn't work out, so I'm unaware of any scheduled CRS events beyond Ridgecrest. San Diego region may want to try to restart, but they will be SCCA as well. Obviously things can change, but I wouldn't be investing money in CRS-specific tires until they do.

BTW, those tires don't look very aggressive. These aren't truck tires, but they're not pure snow tires either:

A tire I've considered, but never bought, so can't vouch for them.

Those Geolandars are basically just all-season passenger car tires, not truck tires. They don't have an aggressive tread like a mud tire, and they don't have the stiff sidewall of a real truck tire, or a rally tire for that matter.

They're great for cute-utes, though.

[eage8]

the tread pattern looks decent... fairly nice big shoulder blocks with seemingly decent tread gap. and the sidewalls have to be stiffer than winter tires... It would probably also hold up to the heat far better than a snow tire would.

It seems like a decent stock-class tire to me...

[noisycricket]

One of our locals ran the same snow tires for 2 or 3 seasons before putting a nail through one in a way that it wasn't repairable.

For an AWD, I don't think tire life means anything at all.

you have pretty soft dirt though...

one of our fields has hard packed clay :) snow tires don't like it much...

But FWIW, the rules regarding diameter and width of the wheel itself remain in place although they're at least allowing a slightly larger offset adjustment on that - "6.2.C.12 Any type wheel may be used provided it complies with the following: Wheels must be of the same diameter and width as the OEM wheel. Wheel offset (backspace) must be within 0.394”(10mm) of original equipment wheel offset."

OEM wheel produced by manufacture? or OEM wheel for that specific car?

My real question...
My 96' Impreza LX has 02' WRX rims on it. I believe the car came with 15's on it and the WRX rims are 16's. So I would need to go back to a 15" rim to remain in the stock class?

Yes, it needs to be the same diameter and width as the stock wheel that came on the car. which is why I have to use my RS 6-spokes (7 in. wide) for snow tires and my LGT snow flakes (6.5 in. wide) for summer tires :(

Edit: it looks like a 96 LX came with 15x6 in. wheels.

[LPPrelude]

Yeah they were a 15x6 I am looking at getting 6 team dynamics wheels, but want something used (fingers crossed) as I don't really have a lot of money to dish out for this.

[scrappy doo]

i've ran these geolanders on my OBS for a year or so, the sidewalls are actually not as stiff as i'd like them to be. they work well in mud and snow though, and i've ran a couple rallyx for fun and done all right. next set of tires will be different though.

[u3b3rg33k]

What about these:
http://www.nokiantires.com/tyre?id=11952&group=2.02&name=Nokian%20Vatiiva%20A/T
They are NOT snow tires.
http://www.nokiantires.com/files/nokiantires/2008/vatiiva_at_lg.jpg

They might be a little tall, but they go down to 14" rim sizes.

Those are what Utecht used on his Mustang.

You can see a shot of a used one @3:09

Then again I think he knocked at least one off the bead every time he used them but you won't exactly be bouncing off of berms at stage speed so who knows.
