15" Konig Heliums+tire weight info

[CASTREX]

Some more yaris related information in case anyone cares...

I just fit my new 15" Konig Helium rims with a set of super cool tires.
Hankook R-s2 W212 205/50ZR15 (treadwear 200).

The rims weight 11.8lbs.

The rim + tire weights 31.68 lbs

If I compare this with the 33lbs OEM alloys I just JUST reduce 1.3lbs (sucks... you might say) but in the other hand I´m going to be running on a much wider and super grippy tire so I´m quite happy with the result.

Some thing else. This size of tire is a little bit to wide for the heliums... so if you have those rims... you should probably go with 195 instead of 205.

sweet i plan on buying a set of silver heliums do u have any pics?

[CASTREX]

Post some pics later... my camera has no batteries

[Black Yaris]

what is the width on the heliums? I am running a 15x7 with a 225/50 and she looks fine, maybe a tad wide, but I love the handling with the 225's

[CASTREX]

The heliums are 6.5" wide.

It's weird because 205 tires should be a perfect match for this size of rim. I dunno if it has to do annything with the tires being ZR or something like that. I tought 205 will always be 205 no matter the brand or kind of tire you are using.

Please correct me if I'm wrong.

205 is shoulder to shoulder (the shoulder starts where the smooth side wall ends) not the footprint of the tire. Perfect example my tires are 225/50VR15 g-force sports, my wife's tires are 225/50HR16 Potenza G009's my tires actually have a wider footprint than hers for 2 reasons (1)brand/model & (2) speed rating. I mean you could take the same tire I have and a BFG traction TA same speed rating and size, There still will be a bit of difference in the footprint, it is all in how the tire is designed.

This surprises me as I thought the oem alloy would be lighter. My stock steel wheels and tires weigh 33 lbs(w/o covers). But you did get a wider tire and save weight so thats sweet.

The reason is simple. Race tires like the Hankook 212's or Falken Azenis run REALLY wide. Technically yes, a 205 tire should be ok on a 7" wide wheel, but I come from the BMW camp, where you run the BEST size for that width of wheel. Examples:

8'5" wheel 245/255 max
8" wheel 235
7.5" wheel 215/225 max
7" wheel 205
6.5" wheel 195
6" wheel 185
etc etc

Problem is you have every mustang/camaro owner telling you.."Dude I run 275 Nitto's with 8" wide wheels and it's fine." And in reality his car handles like crap (Not that domestic owners care).

should have got the Feathers

actual section width is based on wheel width and the tire itself (should be consistent through out the model in a given size).

go on tire rack and look up the "specs" of some tires you'll see the differences, it is more dependent on the "style" (max performance vs. all seasons) then it is speed rating (although most max performance tires have a higher speed rating).

and the # posted on the tire is rarely "exactly" what the actual tire you have on your wheel is.

Anyone know what the stock 14" steelies with tires weigh?? I want to get the 16" Feathers on 195 Azenis'

Thats not 100% correct. Each tire manufacturer measures width a bit different. A 315 Nitto is as wide as a 295 BFG,Goodyear or Kumho tire. There is no real measurment standard. Your "best sizing" list is fine for certain cases, but for AWD cars, or heavier cars you will be better off going a bit wider as long as you have the correct offset and clearance.

Too narrow or too wide of a tire on a given rim is not good for handling. I would rather be on the wide side than the narrow side. The streched sidewall deal that people like right now is horrible for handling.

Just for reference, here's some photos of my Yaris with stock Bridgestones
(185/60R15) on 15" Heliums. I might go a little wider after I wear out these tires..............Mike

That's also not 100% correct. Too narrow (within reason) will almost always perform better than too wide. A 275 on a 8" wheel will deflect a lot in turns, whereas a 225, a bit too narrow won't budge in a turn.

While I see that you like to try and correct me. I have owned and raced 7 BMW's and a few were ///M cars, I understand handling and tires more than I could type in a paragraph. I used to do the rolling diameter calculations just for the heck of it with the formula memorized. Sure a 245 Kumho MX or Bridgestone S-03 will run wider than say a Dunlop SP Sport 9000 or Kumho Exsta Supra 712, but my above recommendations are damn close to spot on.

I realize you're a domestic owner at heart, and I...well...hate the damn cars, barring the Vettes, a car that can actually perform ALL AROUND well, and not be built like poo. But there's no need to argue with me on common sense things. A 245 tire will always perform better than a 265 on a 8" wheel, it fits the wheel correctly giving more precise handling. And no, I don't run euro stretched tires, just CORRECT for the wheel, that's all.

Those look really nice. When those wear out, you might try a 195/55 15 to get some more rubber on the road, not be too wide for 6.5" wide wheels, keep weight down, and keep gas mileage in check (by minimizing rolling resistance).

It amazes me how much "sportier" those 185/60's look when placed on a correct wheel width and a farther out offset, I'm sure it makes them stick better too, less deflection because the wheel is wider to better hold the tire in place.

maybe Autox is a different animal.

but I've pulled better times with my 275/40 on a 8" wheel then i did with a 245/45 on an 8.5"

same car just different wheels/tires

and the 275s were more worn.

I understand that Proper size is key to optimal handling but stating that it will "ALWAYS" perform better isn't true.

the 275 on an 8" wheel isn't ideal but when restricted to 8" for either $$ or class purposes it's better than a small tire (assuming it doesn't cause any other adverse effects of rubbing, breaking things, not heating up enough yada yada) (when talking about autox).

i refer to Autox b/c that's what I know, i'm not a road racer (yet ;) ).

It looks nice but from the pics it dont look lower to me so it makes the rims look like a very nice stock upgrade.

You are correct. The car is not lowered, yet. I'd like to lower it, but it snows once in awhile and the roads aren't super smooth here. Plus, there's always plenty of roadkill to avoid, and some of the roadkill can be pretty large
