Wheel weight. When is it too much.

Just bought new wheels and tires. I went from the stock 225/60/18's to
255/55/18's with new chrome. I know the stock wheels are supposed to
weigh around 56lbs. This current wheel tire combo is about 70lbs. Will the 14lb
difference be noticible in anyway negative. What is your new wheel weight?

That's a significant weight increase, especially considering the new wheels are only 18's. You'll likely notice a difference. I hope you've got a Hemi.

Less is more

For most people, under "Normal" driving conditions (whatever that is) you will never notice any difference in whel weight (so relax). The reason so much emphasis is put on wheel weight is that it is "Unsprung Weight". All parts of the vehicle wheels, brakes etc.. that come before the shock absorbers are unsprung. Every bump in the road moves the unsprung weight, and the shocks and springs have to dampen the shock and the rebound of the shock.

So, less unsprung weight is better, more is worse. If you're not super concerned with pushing the edge of the envelope, then disregard the weight and get the wheels and tires you really want. If racing the car is of paramount importance then pay close attention to your unsprung weight.

Happy Motoring!

What tires did you buy? 14lbs doesn't seem right. 70lbs sounds like a 22" wheel.
Here are some tire weights for 255/55/18 that I believe are correct.
Dunlop SP Sport 31lbs
Toyo Proxes S/T 34lbs
BFGoodrich g-Force T/A KDW-2 35lbs
Pirelli PZero Rosso 35lbs
Michelin 4x4 Diamaris 32lbs
I havn't weighed the stock rims but the dealer told me the 18" rims are 24lbs.
So the Conti's self sealers should weigh around 32lbs. Without the selfsealing goo, the tire even gets lighter, by 4lbs or so if I have my facts straight.

Hankook Ventus ST RH06 Tires

The tires I got are Hankook Ventus ST RH06 255/55/18.
I am going according to the shipping weight (tire on new wheel inflated)
70lbs. Am I calculating the weight incorrectly?

Shipping weight should include box and packing materials.
Don't know the weight of the box/pack materials.
When you get your wheels, please let us know what your wheels weigh in at.
Also, the 70lbs may only be an estimate.

Hankook Ventus ST RH06 Tires

I have the wheels. The shipping packaging was only 2 pieces
of cardboard the same diameter of the wheel on both sides
of the wheel. Just weighed one of them 1 on a bathroom scale
and it's about 66lbs. I have heard that the cheaper price chrome rims were alot heavier than forged etc,.
Man if I would have went 20 or 22 I don't even want to think
of what the weight might have been. What's the weight of
you guys updated wheel/tire combo and what size wheel?
