Stock wheel weight/ Rota wheel weight [Archive]

Stock wheel with 195/60/15 rubber = 39.5lbs

Rota "Spoom" with P700Z 205/50/15 = 32lbs

P700Z on a real Spoon (Desmond's) 205/50/15 = 28.5lbs

Some of you have no idea what 8lb savings of rotating mass can do for our cars.

Speed and handling.

P.S.
18inch "bling, bling rice crap" can suck it.

:D I'm going to suck crap and get some konigs, no bling bling, but I know it will still suck crap for you

wrong profile tire, 205 55 15 is recomended. pirelli tires are heavier than kumho's?

wrong profile tire

who the phuck says it's the wrong profile???

I will take a concrete tyre over a POS Kumho BTW.
Not sure which is lighter.

15's and 50 series go hand N hand in my garage, sorry you don't agree.

what's up!

the people at tirerack and discount tire, unless you want to throw off your speedometer and mileage.

actually Kumho escta 712 handle better(rain) and are not as noisey as P700Z. P700Z tires are also cheaper than 712 and P700Z has a harder compound, they're still very good tires.

I would take Pirelli's over any ruber! PERIOD!
P7000 or the new PzeroNERO! Both would be an excellent choice. Both in 215/45/17 @ ~$145 ea.

sorry, but you are incorrect.

712's are the one of the loudest tyres I've every owned and their 280+ tread wear is not what i consider "harder" than the 700Z's 140 tread wear.

best tyre for the buck ANYWHERE, period.

WRONG

Generally the higher this number the longer wearing (harder a tire is)

so a 280 tire will last longer or be "harder" than a 140 tire.

If you want 140 great, but don't trash a tire for being longer wearing than another

205's are too small to retain stock gearing, I would like to see some pictures but unless the car is lowered alot it would look like a monster truck.

I ran 205/50/15's Kumho victoracers in stock class and my car looked stupid. I run 225/50/15's now and they are just a bit smaller than stock about .3 inches, the 205's were over an inch smaller and almost 5% difference in the speedo reading. You should try to stay within 1% of stock.

ColinCivicSiR-

Did you run out of gearing with the 205/50/15's on the autocross course or just on the road?

I didn't know stocks weighed that much. I was going to get some Racing Harts S7s in 17's with 205/40/17 tires (preferably kumho tires). Do you think those weigh less than stockies? - sorry i'm a n00b :D ;)

I sure wish I did, tho!:(

Can you run 215/55/15s? Is that a rare size?

That is a good question, Where I race, here in calgary with the Calgary sports car club we see some pretty high speeds, and we use 3rd gear often. We autocross on some wierd venues, a high banked oval and a road course. We alternate venues for events but we see pretty high speeds on the high banking, and on the back straight of the road coarse.

As you all know we hit the rev limiter pretty early on this car so I haven't really noticed a difference in times. On "normal" autocross courses I think it would make a difference, but I changed to the 225's before doing any parking lot or airport events where the speeds are lower.

"Some of you have no idea what 8lb savings of rotating mass can do for our cars."

I do! The difference is unbelievable -- turn in, acceleration, ride, you name it; 8lbs is a huge difference.

well arn't you just the einstien.....some of us do understand the difference......but 205s are too small, for many reasons, not just gearing. I found that the roll over and wear was too much, this was related to the tire size. Our cars are very hard on front tires, this is because of the large 25.4mm sway bar and the small 15 mm rear and the weight on the front and the strut suspension.

225, are a better choice because they do not roll over as much given the right pressure for the car. I have done much testing and can say this is so.

You are right that lighter is better when it comes to rotational mass but there are other considerations.

That being said 205, for street driveing would be better but with a higher aspect ratio. If you want to ride around on cookie cutters for street driving then go ahead.....it still looks like a monster truck.

B18cxr , preech on brotha.

I had rota c8's on my lsat car with kumho 712's (cant beat the price) 205/50/15's light and effective LOVED THEM!

now presently i have 15 spoom rims :) still deciding what tires to go with, maybe azenis? (little heavy, but alot stiffer sidewall,) or some so3's MMmmm.. we'll see..

IM the ANTI BLING BLING:)

WRONG

Ooops, you are correct about the higher the number the harder, i got caught up in my typing trying to state that the 700's are a chit load softer than the 712's....

P700Z tires are also cheaper than 712 and P700Z has a harder compound, they're still very good tires.

was the point i was trying to correct.

I've logged nearly 20k miles on a set of 712s (205/45/16) on my '90 Si, and just bought a set in 205/45/17 and a set of Rota subzeros. While I would auto cross on a a tire that is biased more toward dry grip, I find the Kumho 712 to be an exemplary street tire with good dry grip, excellent wet grip, good crisp turn in, exceptional treadwear, and an acceptable level of noise. This is all irrespective of the fact that they are also the cheapest thing going. I reccomend them highly. Go to www.tirerack.com and look at reviews left by people who own them.

Well, while we're talking about tires, I need some advice from those of you with experience.

I want to AutoX, but its a daily driver, and I see rain often but hardly ever ice or snow (like one or two days a year).

I'd like a good daily tire that will last about 40Kmiles that is also a decent AutoX tire...doesnt have to be the best, just somewhere in between stock and full on AutoX. Allow me to illustrate:

1(AutoX-only tire)---2---3(the tire I want)---4---5(an all-season like stock)

Price is pretty flexible...and I'd prefer not to get something with a super-tiny side profile, but a different size from stock might be in order, too. For this set, I'm planning to keep the stock rims.

I have 16" Black VOLK TE-37s on my EP w/ 205/45zr/16 Paradas im wondering how much weight i shaved. Im guessing I shaved a good 8 pounds of at least.

I think.....18's are muy sexy. Make the car super fast so you can FILL Them with happy brakes. 15's....small rims just look incorrect on a car imo

Kumho's 712 are the best bang for the buck. if you want to spend money,then go for Bridgestone's.

Does any one know if 14's will fit on our car? Autocross only of course.

Bridgestone whats? And what about sizes for the stock rims? Sorry, but I have no experience with tires beyond the #%&*!@ Firestones on the other civic.

OK, Im starting to narrow it down to these:

Kumho Ecsta 712s
205/55/15
VR 360 AA/A
20.4 lbs

Any warnings?

yes 14's will fit on our eps

i have 14 x i believe 5 1/2 steel wheels with Nitto NT-555R drag radials for obviously drag racing and they clear the calipers barely.
