I have a question
 

hey guys my back tires are horrible right now there cracking and everything now its starting to feel like its thumping or something when driveing is this because of the tire do u think or the rim?

you could have a flat spotted tire or something, but more than likely it's not the rim if it feels like a thump. If your rim is bent, the tire will probably lose air (buy not always), but the tire will remain the same shape pretty much.

haha i fixed my thumping with a set of new tires but that lowerd my money for mods ;( but now i still have 700 or 800$ but u have to remmember ihave 200 payment due in may plus that is security money in case something should happen o well thanx for all the help later
