Today I hit a big pothole on the road, hard. My 21 inch GTS wheels seem unbent, however, one of the tires developed a big bubble, i have had this on my old Range Rover Sport, never bothered to fix it and it never gave me any problems.
Should I bother to get a new tire? These tires have less than 2000 miles on them and i really dont feel any vibrations etc.

Second question: under somewhat spirited driving, the engine temperature goes over the mid point, about quarter point until the next mark. Should i be worried? i dont remember any of my old cars go over the mid point no matter how hard i drive. It does return to normal if i ease down on the gas.

attached is a picture. Thanks guys.

 

I would definitely replace the tire. The metal spindles inside the tire have broken causing the bubble to appear. This rupture has significantly increased your chance of a blowout. I would immediately replace my tire just for peace of mind.

 

+1

Replace immediately. I just had this happen.

 

replace it immediately!! about the engine overheat, same thing happens to me when i drive fast in tunnels, but that's it.

 

Yes, the integrity of the tire is compromised... just think of worst case scenario if you need an extra push to shell out the money for a new tire, i.e. friends/family in the car with you when it DOES blow. Simply not worth the risk - replace it asap.

You have a giant V8 moving 98 tons of mass in 'spirited driving'. She's gonna get warm

 

+1 for replacing the tire.. my engine temps go past the mid point just like yours when i drive it hard.

 

Replace the tire - if not for yourself then for those around you that could be hurt when it blows.

 

Thanks guys. I will get it replaced asap!

 

while your at it, CLEAN YOUR RIMS

and about the overheating, its normal

 

I literally JUST got it washed a few days before, the brake dust is crazy!

 

is that front wheel or rear wheel?
your rims look stained but i cant really be sure about that i guess its just really bad brake dust

 

first of all, the dust on these brakes is instant. i get my car washed and it's dirty after one drive.

i had a bubble on my audi s4 after few weeks. i was advise to replace it. i tried to get the dealer and the tire manufacture to help but no one would pay for it. i paid for it fear that the tire may blow!

 

I got a bubble on my front driver's side tire too on my '09 CTTS .. odd thing was I don't remember hitting a pot hole. Just replaced the tire ..

 

its's front... ok i guess its dust with a lil bit of dirt
