who give a **** about stock.

His front rubber is not stock.

OEM 19 Inch: 225/40R19; 245/40R19
Sidewall: Front 3.5 Inches Rear 3.8 Inches
Front Diameter: 26 Rear Diameter: 26.6


OP Setup: 245/35/19; 275/35/19 or 275/30/19
Sidewall Front 3.3 Inches Rear 3.7 Inches or 3.2 Inches
Front Diameter: 25.6 (0.4 smaller then Stock) Rear Diameter 275/35/19 26.4 OMG OMG OMG OMG OMG IT'S 0.2 smaller then stock OOOOOOOOOOOOOHHHHH MYYYYYYYYYYY GOOOOOOOOOOOOOOOOOOOOOOOSHHHHHHHHHHH
and 275/30/19 25.4 (1.2 Smaller then stock) OMG OMG OMG OMG OMG OMG

 

The SPC camber arm kit for the G35 came with toe bolts which were installed along with the arms prior to alignment. I went next door to the place I got my tires from for the alignment and can only assume it was run by idiots.

Anyways, how do you guys feel about mixing tires? I don't plan on tracking my car, just need them for street use.

 

the only other reason I'd suggest running a 35 is the inner sidewall. As you lower the car or ad negative camber there is very little sidewall between the wheel and the pavement. How little depends on the tire manufacturer. Talking from experience, I've torn or sliced the inner sidewall on a 30 series twice already. I decided with the new wheels I'm going back to 35's.

 

ah, disregard my last post. You're asking about running mismatched tires as opposed to the size question.

 

so you people are telling me i im buying the wrong tires for my rims? dropped on my z-htech
Rim spec are
19x9.5 (F)
19x.11 (R)

getting 245/35/19 (F) and 285/30/19 (R)

 

This logic makes no sense, you try to keep the front tire close to the same diameter as stock, but not the rear, why?

 

This argument makes me sad. Perhaps someone can translate it into Russian?

Bottom line is, if you have the choice, go for 275/35/19 or 285/35/19.

 

Everyone seems to want to keep the tires the same height as stock. How come people are choosing 245/35/19s for the front? 255/35/19s are a closer match.

For easy comparison:

The difference in height between a 245/35/19 and a 255/35/19 is only 7mm, I agree that 255/35/19 is a better match though and what I would run

 

35 cause its what i have and i can validate nothing is wrong with it and it feels amazing

 

It is slightly closer to the stock diameter, but on an 8.5in front rim (such as I have) 255/35/19 is not recommended, at least according to this site which says it is OK for 9.5-10.0 inches. That's strange as 245/35/19 is recommended for 8.0 to 9.5. I think the site should read 8.5-10.0 inches for 255/35/19...
