Just a minor speculation of tire weight. (Or wheel weight between Si rims?)

SlammedBlueEM2 · 05-19-2004

Yesterday I got a new set of Si rims to replace my current ones but before I purchased them, I had to take off my current ones to adjust the height of my car. My current tires are Bridgestone Potenza S-03s in 205/55-15. Then I was off. When I got home, I noticed that my new Si wheels (which came off an 03 EX and the stock tires) were considerably heavier! WTF? I knew it couldn't have been the wheel because they're exactly the same (at least they should be especially in this case). For instance, I could just grab my old rim with one arm and toss it considerably far (on the grass), but with my new wheels, I was bound to hurt my back if I didn't use two hands.

I know the 205/55 is smaller than the 185/65 but I'm just curious, are all-season tires really THAT heavy? When I think about it, the only other wheel tire combo I've held were some 205/50s on 95 GS-R rims (which are lighter than my set-up). But when I had some 195/60-15s (all-season performance... Yoko H4s) on my steelies, the combo was quite heavy. I wanna talk tire weight.

Some tires are heavier than others.... the stock shitstones are surprisingly heavy. As per usual, heavy has something to do with cheap, I'm sure they've got lots of steel in them and the rubber compound is pretty hard. My Kumho MXs are about 18 lbs, all be it they're 205/50s, but the Firestones are about 24.

So an all-season tire with harder tread is composed of more, heavier material than say a performance tire? I understand tire weights vary by brand, but is it also based on type of tire?

Now this is odd.

The Firestone FR690 weighs about 20-21lbs
The Bridgestone S-03 weighs 23lbs

Both of these #s come from Bridgestone.com.

Is this really a tire issue or a wheel issue? I guess the only way I'm gonna find out for sure is when I get new tires put on my new 03 EX wheels.
