New shoes for the tl.

How y'all doing,
Just like To say happy Hanukkah, merry Christmas to all my brothers and sisters on the forum. From my family to yours, may all your dreams come true, and most of all, a healthy and a happy new year. As the title states, I put new shoes on the car yesterday. Now before you all kill me, realize I drive about 26 to 29 thousand a year. It's not a race car or a track car. I chose the fallken Ziex 950 a/s, of course in 235/45/17. Tire has a 45,000 mile warrenty and I also paid alittle extra for the road hazard, free rotation and balance for the life of the tire. Otd with alignment came to 617. That a good day all day. As for impressions for the day, tire is quiet, but not as quiet as the michilen primacy. Not obtrusively loud though, Grip and traction is better all day every day than the michilens. Side walls seem to be stiffer as the cars cornering seems more controlled and precise. That last observation could be because the tires are new. Not that it snows here where I am, but as for rain, the fallken is better than the old tire as I have owned the 912's on another car of mine in the past. As time rolls on I'll revisit the post and tell you what else I may find good and or bad.

Curious, why didn't you go with 245/45?

honestly the thought never crossed my mind. That is still doable as the tire shop is running a promo. They say if for any reason I don't like them I can switch out for 30 days. I may do that. I wonder if that will change my gas milage at all by adding 10 mm in width. I thought about Firestone Indy 500 as well.

Why would someone put 245/45 R17 tires on a 3G TL? I ask because doing so will negatively affect the speedometer and odometer; both of which will register low compared to actual by making such a tire change.

Any loss in mpg would be worth it to me! I have two sets of tires on my track car and the 205s are much less grippy than the 225s, it makes a nice difference. $600 is a great deal! You must have gotten them on a good winter sale discount. I'm surprised you say they are better than the michilin.

Nothing is better than getting new tires. Best upgrade you can do, hands down. So much fun to feel the difference. Unforetunately for me there will be no new tires on the TL this year. I have to get through another winter with the ones on there. I just put new front tires on the bimmer tho! Would be nice to get a whole season out of them, we will see.

fills in the wheel fender gap, sticks out more around the rim for protection and is more appealing to the eye, it feels like it grips a bit more firmly, and has a more aggressive look from the rear by 5mm of extra rubber. Gas mileage is affected more by tire type than the extra 10mm. Summer performance will definitely eat some mpg vs all seasons. I'm looking at the michelin pilot sport a/s 3+ for my upcoming set. & the only needle I really look at is the rpm, eagle eyeing it on redline.

I suppose what looks good is in the eye of the beholder, but from my perspective, form follows function, and the 245/45 R17s are less functional.

Horseshoez, why would a wider tire throw off speedo/odo. They are wider not taller. The 3G tl base is 235/45 stock. Wider may affect gas mls, as for more tire which equals Rolling resistance. I was under the impression only taller or shorter wheels affect speedo calibration. 45 is still 45 245 is wider.

Yes, 245/45 R17 tires will in fact be both wider and taller than 235/45 R17 tires. What you don't understand is the second element, the "/45" part, is a representation of the sidewall height as expressed as a percentage of the section width. Said another way, 45% of 235mm is 105mm while 45% of 245mm is 110mm.

Long story short, 245/45 R17 tires will definitely negatively affect your speedometer and odometer.

As good as those Michelins may be, they're like Starbucks coffee, overrated and overpriced!

Try the General G-Max AS- 05's if you're looking for an all season tire. You''ll get just as good a performance and you'll save $$ at the same time!

Horseshoez,
I stand corrected and do know about that. I had not thought about that. Yes sir you are correct.

One thing to keep in mind is that the original equipped Michelin 235 was the same height as the aftermarket 245. The 245/45-17 on the TL will have the speedo perfect.
The OEM Michelin's are long gone, maybe 2011 was when the last was sold.

Not saying you're wrong, but that seems a bit illogical to me. Per my GPS, the speedometer and odometer are pretty much spot on and I'm runing aftermarket BFGoodrich tires on my TL in the 235/45 R17 size.

I actually love the General brand, I run the Altimax for winter vs the Blizzaks people debate over.
But for summers, i love the Michelins because they have such a nice smooth sidewall and it looks great to me. The tread pattern as well is very nice. Not to mention overall reliability, wear, grip, and noise. I'm sure the G-Max are great nonetheless.

Also, the speedometer difference is about 1 mph @ 60mph between 235/45 & 245/45. Hardly noticable.

245's won't change "that much" but they will get better gas mileage because the diameter of the tire is larger. And the tire travels over more distance for the number of rotations. But the torque would be slightly reduced.
And the speedo would show you as being slightly slower than what you are going (not so good).. However, the Mileage would be slightly less than what you really traveled.(very good)

I think all speedo's are off a certain amount because tires wear and air pressure may effect it too, because if tires are not inflated fully, it could very slightly effect. But may not be measurable.
The best way to check your speedometer (to see how far off it is) is load Google Earth and mark off 1 mile and then jump in your car, and reset the trip, and see how much difference there is.
This is a very good way to see real distance in miles, because I have a coworker use it for Outside Plant fiber route miles, and it matched perfectly for a 5k run "start to finish" .
So it is very accurate..
