tires and rims questions

[Nettles 400ex]

So my 400ex has stock rear rims on it and i want to get sedona bazookas for the rear. I want to get 20-11-9's. But the rim measured out to be 20-10-8.
Can i run 20-11-9s on that without a problem?

Thanks.

(P.S. are nerf bars worth the money? I hill climb and trail ride.)

If your rims are stock you can run those tires! And nerfs are definitely worth it I broke my ankle ridin a wheeler with no nerfs

You said you have stock rims but they measure 8"? That isn't possible if they are truly stock rims. Stock rims measure 9x8 (9" diameter, 8" across) If yours are measuring 8" diameter, then they are not stock and will not work with those tires. You need to buy 20x11x8 tires to fit your rims.
