PEDDERS SUCCESSFULLY FITS 305s ON ALL 4 CORNERS!

[PQ]

Ok. Fine......

What total outside diameter is are those tires?

Stock diameter?

How tall would a 305/30 R20 be?

305/35 R20 is stock height and outside diameter.

Refer to tire manufacturer's specs for the most accurate tire diameters. We recommend you stay within 0.5" (plus or minus) of the factory tire height in order to maintain accurate vehicle systems. This gives you an acceptable range of 28.2-29.3" diameters. Wheel widths shown are recommended, and only serve as a suggestion for proper fitment/appearance/performance.

Hey.....

I edited my last post........ jerk......




And the point is made. Smaller sidewall.

Stitch is running 25% sidewall.

Stock height on 305s would be 35%

[Stitch]

I believe the overall tire/wheel combo had a diameter of about 26.5", but I'd have to check my notes to make sure, and they're kinda far away...

I choose that tire size because it was the closest in overall diameter to the diameter of the Pedders car's tire/wheel combo, that way, I'd know there wouldn't be any clearance issues.

...and it's probably not wise to refer to one of most knowledgeable moderators on here as "jerk". Let's try to keep Pete's threads clean and informative.

As far as informative goes, I may have rehashed some things but it did bump the thread and I did learn something and we did learn why you chose the tire sizes you have.

I wondered why you chose such thin sidewalls. Now I know.

Let's extend classtime a little here.......

Pete? I have about the same sidewall as stitch does. Problem for me is (other than needing to lose the donk wheels all together) I have NO traction due to thin sidewalls.

Why are thin sidewalls ok on smaller rims? Why is there not as much traction loss?

We choose the tire and wheel size in large part based on the availability of the RE-11 Bridgestones. IMO, they are hands down the best combination of a street / track tire. Weight plays a role as well. The smaller OD worked for us as well effectively creating a rear gear change.

On the new 'Pedders' Camaro we are running 20x10.5 with Michelin 305/35ZR20/XL Pilot Sport PS2s. I poked around looking for an illustration of tire sidewall flex and found this Tire Sidewall Flex Animation Too much tire side wall flex causes instability. Too little side wall flex causes a loss of traction. If the tire can't roll the sidewalls, then the contact patch slips.

What is the perfect tire size? The new ZR1 has Michelin Pilot Sport 2 tires P285/30ZR19 in front and P335/25ZR20 in the rear. The rear rim is a 20x12 the front is 19x10. In these low aspect ratios the tire itself is mission critical. For the ZR1 Chevrolet worked with Michelin to create a Pilot Sport with characteristics for optimum performance. In a practical sense, a taller side wall will protect the rims from impact damage i.e. the unexpected major pot hole. On the drag strip tall side walls that wrinkle are desirable.



The Bridgestone Potenza S001 - 305/25R20 that Stich selected carry a dry performance rating of 8 from the MFG. The RE-11s have a MFG dry performance rating of 10. The S001 wet performance rating is a 9 compared the RE-11 with a 7. The Bridgestone S001 is a good choice, unless you are looking to max out a lap time and prove a point. Nitto NT 05s are very good, but are not available in a 305. Selecting the tire size for your Camaro is a balancing act between tire weight, revs per mile, stiction, brakes and RWHP. If you would like to stay between the lines on a rainy day wet performance could be important too Especially with a 305 up front.

If I have my choice, the Bridgestone RE-11 305/19/30s are on my Camaro, unless some dumb-axx rule prohibits their use because they are too good. Then we go to Michelin Pilot Sport PS2.

Did I just

[GTAHVIT]

wait wut??? dumb ass rule????

[PQ]

So my 22s are not your first choice then. Got it.

this thread is smoking...Pete..u are the MAN

[Info@PeddersUSA.com]

going to be a good time!

[Stitch]

I've ran 2 sets of RE-11's for past events, and I can agree that they are a phenominal tire, but in rainy hills of Western PA, they can be a little scary in the wet. I'll be picking up a second set of wheels for the SS for track days, and either RE's or A6's are going on, depending on what class I decide to shoot for ( unless Nitto comes out with the 305 ). The S001's feel very confident, even in standing water. Even got stuck on the highway in stopped traffic while I was home, because the rain was so bad that visibility was almost nill, and the S001's never gave way. I know they're not the best performing, but I'm very happy with it as a street tire.

My sidewalls are definitely shorter than what I wanted, but my initial measurements were based of the first set of wheels on the Pedder's car, which were 19's. After seeing how everything came together, and now knowing that I have some extra clearance, my next set of tires will be taller. Just wanted to be safe, not sorry. Never good to be the guy who get's a blowout from his own fender. Guess I'll just have to burn through these faster...

Anyone willing to help?

Can't wait to see what the L/28 can do.

[GTAHVIT]

Stitch,

I'm thinking the same... I'm gonna go 10" wide so I need to be in a 295 wide tire.

there are a couple 295 30 20 out there. One is a continenetal and the other a P Zero...

otherwise I'll be in a 295 35 and there are a ton of options out there for that tire...

Need Pete to chime in on a 295 30... See if he's cool with that setup.

[ipimpthisc]

I would love to do a 305 or in the front but i notice something...tell me if u guys have the same issue. When i put the larger tires of front my car wanders side to side on roads that look like rail road tracks... What i mean is that in nyc due to so many cars and heavy vehicles the soad looks like a hump in the middle and to the left and right like a valley all the way down. It make my car track with the shape of the road. I hate it.

Sweet! I'd say that's a go for the 295/30...

Oooorrr... there is a titanic Iceberg reference in there and I'm headed for disaster.....

Tire tread and alignment will make the search in the ruts better or worse. A bit of caster offset, just a half a degree will help minimise it.

305s up front will search the ruts, but it shouldn't be that much worse. My guess is that the caster offset will keep it about the same as you have now. The easiest way to test this on your roads is to install a set of caster eccentrics and dial in that .5 degree stagger. Drive the worst roads and see how it feels. It won't be gone, but it should be much improved. If the result is good then you can move to a 305 front.
