Hey guys. So I got my car lowered on Impuls, but before that the car was pulling to the left and vibration above 70mph. Went and got an alignment and balance done and the car was still pulling to the left and vibrating above 70mph. So the mechanic said that most likely problem was tire (radial) pull. That the tires I had on were not agreeing with my G37. To confirm his theory he rotated just the two front tires. Left to right and right to left and sure enough the car started pulling to the right. They recommend I go to my local Discount Tires and trade in my current tires for some good Michelin tires. So I went to Discount Tires and they even told me that the new tires the Nissan dealer put on the G are pieces of ****. The brand I have now are called Westlake tires in 225 55 17. Never heard of this brand. So now I am going to trade in these piece of **** tires for some Michelin Pilots in 235 55 17. Going a little bid wider all around. Hopefully this resolves the issue and if not well at least I will have some good quality tires on.

 

Westlake = Chinese tire.

Your Nissan dealer shouldn't be cutting costs this low and depending on how long you've had the car, I'd call and let them know it. You didn't buy a 10 year old Sentra, and I'd be curious if the Nissan sales manager allows his family to ride around on such tires. Can't beat Michelin tires though, definitely an upgrade.

 

I was honestly surprised. I bought a 2012 G37 Journey sedan from Mossy Nissan with 30K miles. I was happy that it came with new tires but I never noticed what brand they were until today at Discount Tires when the sales rep said they were Westlake and that they were crappy tires. I was like Westlake??? What the hell brand is that! No wonder I am having tire (radial) pull and the car vibrates. These tires suck!

 

Get yourself a pair of Michelin Pilot Super Sports and never bother with anything else.

 

Those are the ones I am actually getting!

 

Absolute motherflipping best street tire money can buy.

They GRIP all day long, quiet, super smooth, lighter than 90% of tires, and they LAST for easily 25K or more.

 

Gettin' mine put on Friday. The PSS are supposed to be tops on sporty cars. Hell, BMW uses the PSS for the M4 off the show room floor. That should say something in itself. They are a bit costly though.

 

OK boys, update!!!!! Went and traded my crappy new Westlake tires that came with my car from the Nissan dealer. Went to Discount Tires and got some Michelin Pilot a/s/3 in 235 55 17. The Westlakes were 225 55 17. All I can say is WOW!!!! The vibration and car pulling to the right went away! The culprits were those crappy tires. Since I went a little wider all around the car has a wider stance and looks more aggressive. Before I was gonna get spacers, 20mm front and 15mm rear. However, these new Michelins really got rid of the tucked in look. Now all I need is 10mm front and 5mm rear! I am so happy that the car does not vibrate or pull anymore. I had no idea that there was so much differnce between really cheap tires and Michelins! I will post pictures later!

 

Ok guys here are some pictures of my new wider Michelin tires. For spacers I was thinking 5mm rear and 15mm front. What do you guys think? Or any other suggestions.

Rear



Front

 

Shaking at 70mps sounds pretty dangerous haha
Good tires are everything!
Good luck!!
