Hello Everyone!

I know this is probably a dumb question but I have been goolging and calling and now one including the dealership can give me a straight answer.

Can I use 245/45 R17 on my Acura TL 2006? I am hoping it will give me a smoother ride, I hate the low profile tires that make me feel every bump on LA roads.

Original tires are 235/45 R17 and discounttire store looked up on the computer and they said I cant however I think I have seen people do it on this forum but not sure maybe their cars are different years.

Thanks!!

The ride quality, regardless of size, is based on the tire construction, not the size. I know I've said this before, when you look for tires, place the unmounted tire upright and push downward on the tread to see if the tire buckles.
Some will move easily like the DWS, the W4s will move slightly, the S.4 only marginal movement, but some will not move at all. The stiffer the tire, the harsher the ride.
Stick with 245/45-17 though.

You can mount a 245 tire no problem. A lot of shops tell you no because they don’t want to be liable for mounting a different tire size then what the vehicle calls for.

Agreed. Just going between the same size summer tires I've seen big differences in comfort. Going to a taller tire and less performance oriented should make a nice change.

You're welcome! Have you had a chance to try them out in the rain? Or are you one of THOSE people that don't drive in the rain lol.

I havent done anything stupid in the rain.
butt, normal driving in wet conditions doesnt seem scary at all.
the tire evacuates water and I DONT hydroplane like I thought I would.

Now, the scary part is if you dont warm up the tire.
an 80mph stop with cold tires on dry conditions will scare the shit out of you.
i will never do that again.

is it me or is the OP trying to get higher profile tires?
235-45-17 and 245-45-17 are the same height profile... the 245 would only be wider..
someone please correct me if im wrong..?

Bearcat, you got this.

The Section Height is expressed as a percentage of the Section Width.

So for the 235/45, the Section Height is 235mm x 45% = ~105.8mm;
for the 245/45, the Section Height is 245mm x 45% = ~110.3mm.


But it's not quite that simple because it's just a "norm" or an approximation. To get the "correct" answer you have to look at the overall diameter of the individual tire.

For example, the TL stock 235/45-17 Michelin MXM4 stock diameter is 25.6". That's about 0.3" taller than you might expect. IOW - the Section Height is about 4mm taller than the expected 106mm.

BUT the Michelin Pilot Sport AS Plus in 245/45-17 has an overall diameter of 25.7". That's about 0.5mm taller than "standard".

IOW - for the example above both tires are pretty much the same Section Height, but you wouldn't know that if you only looked at the rated size.

You called it while I was typing.
