Hi everyone, I'm new the group and wanted to get your feedback on wheel replacement:

My TSX wagon comes with the 17 inch wheels with 225-50 tires that I want to replace. Should I go with 18 inch (with 225-45 tires) or 19 inch (with 225-40 tires) wheels while factoring looks and performance?

Thanks for your input!

It's mostly personal preference. Have you found rims you like that are available in both 18" and 19" sizes? 19" tires are in general going to be more expensive than 18." If you are planning on keeping close to stock diameter and/or circumference you are going to have to go to a lower profile tire. This in turn is going to transmit more road irregularities and a harsher ride. The tradeoff is better handling.
What are your priorities? What's your budget?

Thanks. My priorities is ride quality and looks, and not so much handling since it's a station wagon. I see the question is mostly how will the look and ride be different for a 40 or 45 series tire. yes/no?

Ride quality: go with 16"
Looks: go with 19"

In all seriousness though I have some input. Aftermarket 18s look fine as long as you're low enough. The wheels and tires will both be cheaper. My oem (v6) tires have a 45 sidewall vs my aftermarket tires 40 sidewall. I can definitely feel a difference between them but it could also be attributed to 18 vs 19 wheel and they are also different brand tires.

Personal preference. I like +1. Looks better without sacrificing too much ride quality.

Plus tire availability/cost.

Plus total wheel & tire mass tradeoff.

Based on your response and my experience with 18s, I would suggest looking at an 18" tire and rim set up. Again a lot is personal preference so start looking

Thank to you all for the input!

I found this cool article from Car and Driver on plus sizing and actual performance data!

I ran oem hfp pds10 245/45/19 last summer , really loved that set up ...way better handling , tires had 1maybe 2 season left so I sold that set up , I didn't want to fork out the money on new tires .!

This year I'm running oem Accord sport rims in 235/45/18
Same spec as V6 tsx. ....they look great and I got them for a good price ...

I did +1 to 18" A-Spec Wheels (2008 TSX) -- looked great, handled great good solid wheel and fantastic ride quality...

40 or 45 series tire doesn't mean anything by itself.

A 245/40 is taller than a 205/45.

I'm using 245/40/18 on my wagon. Type of tires makes a big difference. Mine are Conti DW's. I feel like they ride as soft...or softer than the 215/55/17 Blizzaks that the car uses for winter. Contis also ride better than the stock sized Michelins did.

You'd likely use a 225/40 or 235/40 for 19" wheels. Or 245/35, if such a size exists. There will be more harshness than a 245/40...if we're comparing apples to apples.

Use a suspension that damps better than stock, and you should be fine. The stock TSX suspension is fairly awful.

Go big or go home +7 to 24's...



Haha wtf

I think 19s are perfect given the shape of the big wagon body

soupi

is 235 45 r18 a good tire size to upgrade to 18s?

ulrblitzer

I believe that is the OEM sizing for the V6 18's and most of Honda's 18" sedan offerings.


I'm on 245/40's for a little bit wider contact patch.

I went +1 OEM 18's (V6 version) and they finished the vehicle without having to lower it. Stock was I was looking for though as I was having a hard time finding aftermarket wheels that were flattering on the wagon.

soupi

are the wheels bigger on your tire vs the specs i mentioned?

ulrblitzer

245 - 235 = 10 mm wider

245/40 = 98 mm side wall
235/45 = 105.75 mm side wall

So .. wider but thinner side wall.
