Maybe its just me, but I wouldn't want to be running any spacers when im canyoning. another reason why im against them

Right before putting these on, and I mean during the same install, I got 2 new rear tires put on. They are a different brand that the OEM Potenzas - I got the Kumho Ecsta's. Maybe these tires are a tad bit heavier than the Potenzas and that's what I'm feeling? Now I'm tempted to look into how much these weigh compared to the OEMs

I should have noted that earlier.

Are you kidding me right now. :confused:

Of course that is what you're feeling. You changed your f'n tires man.....looks like not only are the ecstas a couple pounds heavier, but they are going to feel way different because you went from an older balder tire to a new one that is different.

Just.........wow. Changes the tires and thinks the spacers are changing the way his car feels.

Yeah, almost 100% the tires. The weight on them is way out at the edge of the wheel where it has the most effect. Unless you're Michael Schumacher you're not going to notice that little bit of spacer mass around the hub... until the wheel shears off because you forgot to periodically torque them or something.:rofl2:

Heh... blonde moment there. My fault. Appreciate the feedback nonetheless.

Trying to find a tire weight guide but not having much luck. I will chalk up this up to being attributed to the new tires though. Although it still is weird for the car to feel slower and that's one thing I'm not wrong about...whether it was the spacers or the new tires, there is a noticeable different in pick-up...take it for what you will

It was the tires. Move along

Umm yeah...

REO50

275/35R19 100Y Load Range:XL UTQG: 140 A A

Khumo:

275/35R19 (100Y) Load Range:XL UTQG: 280 AA A

Looking at this info you have effectively reduced your grip by 100%

That's where you're feeling the lack in performance

u do realize the RE11 are 200AA and they grip better.. you cant just go by wear rating especially when comparing different brands.

that said, i would never run those tires on any of my cars :icon17:

kenchan 05-04-2015 11:40 AM

here is a blue car

here is a red car

looking at this info the blue car weighs less than red car :tup: :ugh:

Where does the RE 11 come into play here?

That's a whole different topic and tread pattern with different intent to begin with

We're just talking about a red tire and a blue tire right oh wait tires are black... Unless you have the ones that exude different color smoke when you light'em up!!!

Yeah!!!

kenchan 05-04-2015 12:00 PM

wat "information" were you looking at while comparing tires? you only specified the tread wear rating...

unless you were posting that as a joke, then :rofl2: :tup:

kenchan 05-04-2015 12:01 PM

blue car > red car

kenchan 05-04-2015 12:02 PM

red car < blue car

Its in your head.

Exactly tread wear rating is a great place to start isn't it? Less the UTOG softer the compound... Then higher the UTOG harder the compound

OP went higher so in effect lost grip adding to the lackluster performance he now feels.

Just trying to solidify the fact that it wasn't the spacers (there's just no way) and that the tire change is the culprit...

well, considering there are better wearing tires that have much higher level of grip, that is a long shot. take PSS for instance. those wear like frikken all season tire territory (300AA).. and they grip much better than the factory RE050A's or AdvanSports.

RE11's are also 200AA which have better wear than RE050A's...but they are super grippy.

I think the weight difference in tires and sidewall stiffness can give different acceleration feel between the tires. Bridgestones are pretty heavy in general so not sure if it's the weight difference... probably more from tire feel in general and some loss in traction.
