on my '06 6MT sport I ran Yokohama Avid 245/45R18 on all corners, the car stuck like glue to the road...

 

you guys with the 245 fronts, is there inner rubbing issue? Do you need spacers? I called TireRack and one of the CS told me to be aware of inner rubbing.

 

Nope

 

No rubbing at all for me either. feels stock but with less understeer.

Jpr

 

Nice point. Manufacturers often position the car to have slight understeer which is considered safer. In theory, moving to a wider tire up front will reduce understeer.

 

thank you guys. Just bought the 245 Kumho LX Platinum and installed them on the front. They look awesome!!! Perfect fit and aligned with the wheels perfectly! No rubbing at now. Now i am just gonna wait and see how well these Kumho are.

 

you have 18" wheels? can you tell me ur original and new sizes (front and rear). many thx

 

we got guys running 9.5 in rims in the front and sometime even bigger without rubbing issues.. you're only going 20mm larger on your stock whell... you have plenty of room..

Use this link to compare different tire sizes that will work: http://www.1010tires.com/TireSizeCalculator.asp

 

i have the 19" from the G37 Sport Coupe.

Orignal sizes are:
Front 19x8.5 - 225/45R19
Rear 19x9 - 245/40R19

New sizes:
Front and rear both are 245/40R19

Hope this helps.

 

I am running with 19" wheels on my g, with h&r springs

245/40 up front on 9.5" wheels
255/40 rear on 10"

no rubbing issues, car does grip better on corners but at slow turns does feel a bit "heavier" if thats the word. Just more rubber on the road.
Only drawback is Im on my 2nd set of tires due to my camber being a little off so I had some inside tire wear.

 

thx man, how do you like ur kuhmo tires? also any adjustment you have to do get to those 19" rims and tires work correctly? and is it true that all 19x8.5 & 19x9 rims will fit our cars (08 G35S)?

 

i love the kuhmo, very quiet compare to the OEM. The best part about them are the tread life, 60,000 miles. There are a lot of good review for them. No. You do not have to do any adjustment; they fit perfectly if you get the 245. However, just keep in mind the G37 Coupe Sport wheels are staggered, so you can't put the back rims on the front.

The G37 Coupe sport wheels will definitely fit our cars, BUT if you get some other brand, you'll need to determine the offsets and bolt patterns, etc. I am not an expert on wheels, so maybe some other members can give you a better advise.

 

Are the Kuhmo's some of the tires that Obama just put a 100% tarriff on? Are they from China?

 

do you think those sizes will work for 08 G35S sedan? thx!
front: 19" x 9" - 37 - 5/114.3
rear: 19" x 10" - 37 - 5/114.3

 

I am waiting for my OEM tries wear out and get those...
