Hey guys, I have 35x12.50x18 tires on my ‘21 RCSB. I’m wanting to get a matching spare wheel and tire but I thought I’d check with you guys to see if it will fit in the factory spare tire location. It looks like it would, but not with much room to spare. I have Corsa pre tire side exhaust, so exhaust clearance shouldn’t be an issue. Pic attached if anybody’s interested. Thanks all.

I would be interested in the answer as well.

Also, do you have any type of lift in the front suspension to clear your 35" tires?

Polo, I do have a leveling kit on it. It’s the adjustable one that ProRyde makes. Mine is set as low as it will go which I believe is a 1.5 inch level if I remember correctly. I did need to install 1/8 wheel spacers though to give the upper ball joint enough clearance with that size tire on an oem wheel.

I've got a 295/70/R18 on that same rim up there and it fit fine. Looks like it's really close to the same size as yours.

Thanks Static. I think I’ll be good then. I might take one off and do a test fit before I buy another wheel and tire just to be safe.

No problem. Test fit is always a good idea too.

I have 285/70/18 and put spare rim/tire in the bed locked. And took OEM spare completely out. If I get tired of it being in the bed, may have to try it. They are like 34's
