OMG are these any good????

[NikFu S.]

This is kind of a joke question, but I could use the opinion of someone that knows more than me about tires.

front left
front right
rear left
rear right

Looks like theres some kind of burnt crap on my tires.
Worth swapping the rights front to back?

Stop driving?

I just did an autocross yesterday.

My XT6 in Phoenix had tires a little worse than this.
3 different times one bursted right off.
You ever drove 2 blocks with a busted tire?
It's embarassing.
Doing about 5mph with hazards on, people look at you to see whats making that loud WHUTHUMP noise.
Best friend loling his ass off. :/
Good times.

Saw some fuel filters on Ebay, realized mine has probably never been replaced, someone says it should be done every 15k. True, false?
