Opinions on Tires and changing the size from stock....

Ok, i have been told by a few people, one of which is a Lambo tech, not to mess with the size of the tires on a G.

 

I was thinking of putting a 305/30/19 Nitto Invo on the back and factory size on the front. Only reason....Nitto does not make the factory size on the back.

 

People tell me that if you change the tire size, the clutch will wear out fast and it will also wear out the clutches in the differentials.....

 

So what does this mean to all the people out there who have aftermarket wheels/tires on their G's....?

 

I looked at the specs of the tires....The overall diameter of the tires are as follows:

 

Pirelli PZero (which all recommend to put on the car)

 

Front (stock size) 25.5"

Rear (stock size) 26.1"

 

Nitto Invo

 

Front (stock size) 25.51"

Rear (305/30/19) 26.22"

 

This means there is a 0.12" overall difference in the diameter of the factory spec tires and the Nitto at the larger size. This seems like such a tiny difference when actually on the ground (divide in half) that it would be negligible....

 

Thoughts?

 

So if the tech is correct, all cars with different wheels/tires are wearing clutches and differentials out faster......???

 

 

Oh yeah.....did I mention that my G is a Stick Shift???

I had those nittos on my yellow 06 Gallardo twin turbo and they were fine.

The Roll out or OD of those tires are close and should not have a issue. Not all cars have issues when using over sized tires but some do. It depends on how close th OD is to stock, driving conditions and luck. I always say stay with stock but I have seen cars do ok with over sized tires. I have seen cars have issues with stock size but different brands of tires as the OD is not the same from one brand to another.

 

You numbers are very close and should not have a issue. Should being the key word there.

I put Continentals on my 04G last year (harder compound=more mileage per set). I was able to get the stock size for the rear, but had to go with 245 wide on the front. Tire guy said I would be fine since I just went WIDER, not BIGGER. I haven't had any issues. However, I can understand about the differential clutch wear if you go wild on a different size.

I think Allan ran 305s on the rear on the G-TT, not sure...

If a ZR-1 can do 305's so can a G!!!!!!!!

had the 303x30 on rearfor 18000 miles no problems

 

 

Nitto Invo
