Hi all, just gotta 2010 Civic Si sedan (white). Love the car, only 18K.
But I just rotated tires front to back (previous owner skipped this step). And now the car pulls to the right on acceleration, pretty bad too. No camber wear just 1/32 less tread on prev fronts. Searches reveal its a common problem, and alignment may not solve it (!?@$#%$)

What are some recommended alignment shops in Mississauga/Oakville/Toronto that are reputable for Civic Si ?

 

^ B Line does alignment

 

alignment won't fix it.

 

^ what will? why would it be so off after rotation? I can't visibly see a uneven wear on the tires.

 

Slight wear in tires are hard to see by your eye. You obviously have some tire wear. An alignment will cure any future problems(assuming you replace your tires), however it will not cure your pull, if it happened right after your tire rotation. Vehicle pulls are typically caused by camber/caster in the front anyway, which is non adjustable on your vehicle.

 

i would recommend a road force balancing of the tires to chek for tire pull

 

^ thanks! Is that for sure going to rule out the tires and check that they are bad or not? That's prolly a cheaper initial check instead of wasting time/money on alignment first.

 

So my terrible pull to the right on accel. turned out to be a defective front tire. Shop confirmed this by swapping left to right (front) This required inverting/rebalance b/c tires are directional. So then it started pulling hard to the LEFT! So it points to the tire.

Poor mans solution, put the front 2 tires back on the rear (same as when I started) which gives me NO big pull. Downside: I cannot rotate my tires and they will wear unevenly front vs. back. I have 2.5 seasons worth of tread left.

I figure this is better than bothering with changing just 1 or 2 fronts mismatching tread depths with the other 3.

 

I could swear that OEM tires come with a manufacturer's warranty.......

 

I dont have OEM tires. Bought the car 1 year old. Tires are Yokohama S-drive not OEM Michelins. no paperwork from previous owner on yokos

 

^Ah I see. You could always buy a new tire or keep your eyes out for a used set for a lot cheaper. S-drives are great tires and aren't too expensive. I would never drive around with a defective tire personally, no matter how tight I am on money.
Other option is to buy a used tire in exactly the same size and put that on. IMO much safer than a defective tire.

 

^ well, I cannot say the defective tire is a hazard. It just causes a pull to the right, it's smooth as butter and not unevenly worn. No 'lumpy' spots. ....but I understand where you're coming from.

I guess it could be the rubber compound on part of the tire or some internal belts/cords defect (hmm safety concern) arrrrrgggggghhh what to do...

 

ANYTHING that is wrong with your tire is a safety concern.
Everything is designed to work properly. Working properly ensures your safety. If it's not working properly, it's not functioning safely. Your tire is not functioning properly, making your car operate in a way it was not designed to, and is therefore unsafe.
You probably have a shifted belt. The tire does not have to have any visible defects for it to be defective. Watch what happens when the belt shifts some more.
Maybe it's just me, but I don't mess around with stuff like this - I get it fixed quickly.
