My TSX 2010 was sold to me with 19" MDX rims and 245/40/R19 tires. I have noticed on my vehicle that this is a volatile combination leading me to replace my tires very often. Bumps and bruises on the road cause my tires to pinch and bubble a lot where I live because the roads are bad. I spoke with my local tire shop and they recommend reverting back to the stock TSX rims 18" with an increased profile to cushion the impact or even the 17”. What are your thoughts on this advise? My Hyundai accent and Honda accord never blow this many tires in the same roads and they have high profile tires which leads me to believe that there is truth to the logic of switching from low profile rims/tires.

Very good advice.

True story: when my wife and I bought our (former) 2012 GTI, the dealership pressed us heavily to buy a wheel and tire warranty for something like $1,700 (they actually said, if you don't buy this warranty you'll be coming back to us for replacement wheels and tires). I said no thank you and bought a very nice 17" set with Enkei wheels and high end tires, and then sold the OEM 18" set for nearly the cost of the new set.

You can absolutely do this.

You can use one the on-line tire size equivalency calculators and input the factory tire size that came with your car/model. Then you can select a different rim/tire size to match the factory diameter as close as possible. Some people allow a 2% variation but my personal preference is to be within 1%.

I would personally go with the factory tire/rim size for the 2010 TSX (225/50/17 I believe)

You can definitely do this, and you can explore options at the Tire Rack. I think it's a good idea. It's not just about sidewall depth though, because the tires themselves are a big factor. My previous car was a 2001 Saab 9-5 Aero, and even on its 17" rims I knew all about "pothole explosions" that BMW drivers with hard run-flats complained about. I destroyed several rims, both on the stock Michelin summer performance tires and a set of Sumitomo high-performance all-seasons. But then I switched to Continental DWS tires, and all of that stopped. I didn't damage another rim, the pothole explosions ceased, and I got better handling and steering feel too. So, if you're looking on the Tire Rack, check the tire reviews for ride quality to see if clear patterns emerge.

Thanks for your help everyone. So I found someone who happened to be looking for a set of 19" and had 17" TSX stocks for trade. After the trade I threw some Proxes Versado Noir 235/50/r17 tires on them and it is now a noticeably more comfortable drive. The wheel diameter matches the original stock 235/45/r18 for the V6 TSX so my speedometer is now accurate which is a plus. But now with an extra inch of wiggle room for holes I feel safer on the road from holes and bumps.
