    Your wheel specs sound very much like Nissan 240SX stock 7 spoke rims... what car is it for? If you want rally tires you'll need 15" rims (16" rally tires are almost unobtanium in NA). What 15" rims will fit boils down to what fit's over/clears your brake calipers... be careful, you might find 100 diferent rims that match yur specs, but 95 of them won't clear your calipers.

    The car is an 03 Sentra SE-R. I know some 15" Altima rims fit, because that's what I bought to mount my winter tires on. I don't know about other sentra's because I think some come with rear drums instead of 4 wheel discs

    If you already have some that fit, then you know exactly what to get. I'm pretty sure Nissan 240SX 7 spoke rims will fit too.

    There are a lot of options for OEM Nissan 15" wheels in 4x114.3 bolt patterns. 93-01 Altimas, 85-88 Maximas, 89-96 240SXs, 84-89 300ZXs, 07-11 Versas, and I believe a number of the 01+ Sentras as well.

    Interestingly, I know that while the offset is similar, that Versa wheels are dished more than b15 Sentra wheels. In order to fit wheels for a B15 Sentra SE-R (with *much* larger brakes) on my Versa, I needed a 3/6" spacer to clear the caliper.

    Beware of trying to fit other brands wheels, as the center bore on Nissans is large, and typically other import wheels with the right offset and size will require enlargement of the bore (true for certain of Honda, Toyota, Mazda and VW, haven't tried others).

    VW and Honda wheels will also have spherical lug nut seats and finding the right (sperical) lugnuts in a 12mmx1.25mm pitch is difficult to impossible (otherwise you could probably snap up OEM Accord wheels all day long).

    Don't use steelies for rally if you have other options.

    Mark,

    You suggest avoiding steel wheels. Is that to minimize unsprung weight?

    You're suggesting if the spherical lug nuts could be found in the right thread the Accord wheels would be an easy fit?

    Just want to clarify that. I guess I'll start looking for some alloys or used rally wheels off a 240

    No, it has to do with durability and longevity. I'd also think you'd have a hard time finding steelies that would clear the larger brakes on a B15 SE-R.

    To minimize unsprung weight, don't run rally tires! After the weight of your typical rally tire a few pounds here or there in the wheel starts to look meaningless.

    Really, for your typical SCCA-type rallycross event (low speed, tight course, dirt/gras/smooth gravel) you're going to have better results on snow tires (ala Bridgestone Winterforces, and not so much ice tires like Blizzaks).

    There is a desire to run rally tires that I can understand, because that's what the real rally cars run, so that must be better, right? But rallycross isn't stage rally.

    I've run both, and the snows are the way to go with a couple of caveats. If your suspension is so limited in travel (and the B15 is not too bad compared to the b13) or your dampers are so worn out, that the tire ends up absorbing a lot of the force that the suspension is supposed to be doing, you will de-bead a lot of tires running street tires. that's not only inconvenient, but dangerous.

    I came inches from rolling my rallycross car (B13 SE-R) when I hooked a fairly minimal rut and de-beaded the tire, causing the rim to dig in. If I hadn't already been counter-steering for the next turn, I would have gone over. I was running OEM struts that were completely worn out, and actually had wedges in my springs to increase the effective rate (transferring even more impact into the sidewall) at the time. I was also driving at the very limit chasing a championship. Afterward I got rally tires, and didn't de-bead them, but the unsprung weight and rotational mass was very noticeable in the performance of the car.

    Eventually I got a decent set of AGX's for the car, pulled the wedges and went back to snow tires. Much, much better all-around.

    You're suggesting if the spherical lug nuts could be found in the right thread the Accord wheels would be an easy fit?
    Well, they'd be plentiful. You'd still have to have the center bore enlarged. Craigslist (at least around here) seems to be half ads for kids trying to sell the stock wheels off their '90s Accords.

    Just want to clarify that. I guess I'll start looking for some alloys or used rally wheels off a 240
    You'll probably have good luck with people selling their 240sx wheels, as nobody wants to roll on stock in that crowd

    In a junkyard you'll probably find more in the way of Altima wheels.

    The steelies that my snows are mounted on are off an altima and they clear fine. I dont know what the alloys would be like though.

    steel wheels bend. especially when paired with rally tires - the tire is stronger than the wheel.

    I have a line on a set of steelies but I'm still waiting on word about some alloys. What sort of tire should I look into for rallycross? Snows, rally specific gravels etc? I'm just getting into it so I dont want to lay out too much and it turn out its not for me

    Go run with some street tires for an event or two then. Seriously. You will still have fun, you can still be competitive, and most importantly, why spend money prepping your car for something you're not even sure you want to do?
