whats the difference, advantage, or suggestion on which size to go with?

 

the sidewall is a little shorter on the 30 series...

if you have rubbing issues...the 30 series will help relieve that. on my last wheels...my 275/35/19's rubbed so i switched to 30 series and that solved the problem instantly.

 

275/30/19 is the wrong size for the coupe, and is shorter than a 245/35/19 which is normally used on the front of a coupe, bad choice IMO

 

If youre gonna go with /30 , go with a 285-295.

 

Neither. Go with 285/35/19 or 295/30/19.

 

ok..

the front is 245 35 19..

the rear is what im tryin to decide on.. i guess 275 35 19 is the wiser choice. i dont know why shops keep sayin to go with 275 30 19

 

Because most shops don't realize that you have a stagger and need the rears to be taller than the fronts. They're trying to match front / rear, but 275/30 is marginally shorter than 245/35.

 

+1

285/35/19 is very, very close to the OEM rear tire diameter.

 

245/40ZR19 (98Y) XL 240 AA A 1653 lbs. 50 psi 10/32" 27 lbs. 8-9.5" 8.5" 9.8" 8.5" 26.7"

275/35ZR19 (100Y) XL 240 AA A 1764 lbs. 50 psi 10/32" 30 lbs. 9-11" 9.5" 10.9" 9.1" 26.6"


But 275/35/19 is the exact OD as the stock tire. The numbers above are a copy and paste from the tire specifications @ TireRack for the SP Sport Maxx Tire. The bolded numbers are the size, and the diameter. The other nos. have to do with load range @ 50PSI, tread depth, tire weight, rim width range, and recommended rim width.

I'm going with 245/35/19 and 275/35/19. The shop said most people go with the 275/30/19 because they like the look of the rear being lower.

I'm not into the speed boat effect so I went with the wheels that according to the sales guy, are "supposed" to be used.

But other shops says that the 275/30/19 will "LOOK" as tall as the 245/35/19 because the 275 are wider, which makes the sidewall look the same height.

Which is why most people go to the 30 route.

I was told that the 275/35/19 would not rub on my stock sports suspension, so I went with that.

Falkens 452 for the MTFW. Decently priced, low road noise, and has some of the best rating at tires.com.

 

255/35/19 is also right at the same OD as the OEM fronts.

 

Yes, but when installed a common 10.5" wheel, the stretch of the tire will make the overall diameter even shorter, resulting in a greater difference from stock. A 285/35/19 on a 10.5" wheel, being still slightly stretched, will result in an almost exact match for the OEM diameter. But really, we are arguing semantics here, 275-285/35/19 are both the correct sizes to use, and are less than 1% difference from stock, the change in diameter due to tire wear is probably more signicant than this.

 

Yep, you're RIGHT But, I read nothing about a 10.5" wheel

I'm just betting on the 50+% chance that it is, since that is the size mostly used here

 

ok.. so in summary.. which is the best tire size to get???

you guys are confusing me. LOL
