18" tires and weight comparison + special ending

bigjae1976 · 01-18-2010, 08:41 PM

I'm in the market for a set of 18" tires (235/40R18 and 265/35R18s). I just need a decent performing, low cost set of summer tires. So I've narrowed it down to Sumitomo HTR ZIII and General Exclaim UHPs.

Sumi's weigh 24/27 lbs and the UHPs weigh 21/24 lbs. The Direzza Star Specs are 26/28. I would think that 3 lbs per axle would make a big difference in MPG.

Now, what would be considered a light tire for a 265/35R18? About 25 lbs?

The special ending is my rant about the worst tires ever.

need to replace my Goodyear Eagle GT A/S since they totally suck. Between 3 bubbled sidewalls (read: 3 new tires) and 2 that are leaking around the bead (tire issue, not a wheel issue since other tires don't leak), I'm tired of these tires. It wouldn't be so bad if these didn't handle like I'm driving on roads greased with crisco.

Goodyear Eagle GT A/S + CF sidewall = worst tire ever.

/rant...I hope you weren't expecting a NWS pic or something.

Forget tire weight in this case...the differences in grip levels and handling between the HTRZ3 and Exclaim UHP will *far* outweigh (no pun intended) differences in tire weight. The HTRZ3 has faster steering response and more dry grip/cornering, while the Exclaim UHP has a softer ride and longer wear.

You read my mind. This would have been my next question. It sounds like you're a tire salesman or something.

Actually OP has a good topic started here. I just weighed my 265/35/18's and they are 27lbs. I am slightly shocked as I was expecting about 22lbs based on something I read. Do we have a tire weight database that I havent found yet? I wont mention the cheap arse brand I'm talking about

I personally have driven on the track with Z1SS's and they have been doing great for me. The best bang for the buck street/track tire that does not get greasy after a few outings.
