Hi everybody,

also in Germany my normal tire Combo(Michelin PS2 315/25 R19) is not avaible any more and I will Switch to Michelin PSS 305/30 R19. Is it possible to ride and install it on 12" wide tire or the tire is to wide? The tires are OZ Ultraleggera HLT.

Check the spec sheet on the tires. It states the acceptable rim width range.

I have those same tires and I think my wheels are 12" wide but I'm not sure.

 

yes absolutely it will work 100%

 

FYI Michelin specs a 10.5" to 11.5" wheel for that size tire.

BTW what front tire do you intend on running with the 305/30R19 rear tire? The 305/30R19 is 26.3" tall, so you will need a very tall tire (that will rub) unless you have removed the awd system.

PSS 305/30/19 works well on 12" rim, I'm running this setup no problems

BTW when measured PSS 305/30/19 against 315/25/19 Nitto Invo's, PSS tires where 1" wider...

 

PSS 305/30/19 I have this on my car on 11" 997 wheels and they look bulged out. I think a 12" would make them fit almost flush and look good.

 

I run a 235/40 19 in the front. That makes the front just a little taller than the rear like OE ratios. There is absolutely no rubbing in the front on OE or H&R springs. No rubbing on the rear on OE but slight rubbing on the plastic inner fenders under compression with the H&R's.

 

A 305 wifit on a 10.5 rim. You have uber room

 

997.1 GT3 OEM fitment is a 305/30/19 on a 12" rim.

 

sounds good, thank you all for the replies.
I bought them today and after the Installation I will Report and upload a Picture.

 

What front size tire did you run? 235/40 like sinKing said?

I just ordered ADV.1's in a 19x8.5 19x12 setup. I'm going to do the PSS 305's but want to make sure I get the right front tire.

I'm lowered on H&R.

 

Im running 235/35 R19 and Im happy.

 

All tire height specs below are specific to the Michelin PSS (except for the stock sizing), not calculated from the size.

I wanted to run a 305/30R19 (26.3" tall) rear tire, but stayed with a 295/30R19 (26.0" tall) rear tire. I new I couldn't go with a taller tire, since my current tire already rubs at full steering lock.

Since my 245/35R19 is 25.8" tall, I didn't want a bigger front to rear differential.
Front = 25.8"
Rear = 26.0"
Front to rear differential = 0.8%

Stock
Front = 25.3"
Rear = 24.9"
Front to rear differential -1.6%

Total difference between my setup and the stock setup = 2.4%

With a 305/30R19 on the rear and a 245/35R19 on the front, I felt it would have been too much.
Front = 25.8"
Rear = 26.3"
Front to rear differential = 1.9%

Total difference between the 305 setup and the stock setup = 3.5%

If a 235/40R19 (26.4" tall) which is taller, but more narrow would clear, than it might be the best setup.

Here's the 235/40R19 and 305/30R19 specs.
Front = 26.4"
Rear = 26.3"
Front to rear differential = -0.4%

Total difference between this setup and the stock setup = 1.2%

Of course, then the 305/30R19 would probably rub with my current offsets.

Okay, I'm done rambling.

could you share your widths/offsets so i can compare to what i have coming and see if i'm going to have more or less inner fender clearance?

 

My wheels are Champion 19x8.5" front and 19x11" rear. I will have to measure the offsets.

I'll see if I can get it done tonight.

FYI my old 295/30R19 has rubbed on the inside and outside. I believe the ride height was much lower when it rubbed. I have had no rubbing on the rear with my current setup and alignment.
