Questions on using 235/45-17 on 7.5 width wheels
Thanks for all who replied recommending wheel selection. I decided on the Moda R6 with 235/45-17 Sumitomo HTR+ and called Tire Rack ready to order when the Rep questioned my decision on the 235/45 for my tires on my Max (2k2 Max SE) stating that the overall diameter would be 25.3 and that I should keep the diameter around 26 because of possible issues with suspension, ride, etc., which could affect my warranty if I decided on 235/45. He told me I should go 235/50 which would be a 26.3 diameter. He stated the OEM tires/wheels have a 25.9 diameter. He caught me by surprise with this and I told him I would think about it and call him back. I know members here have used 235/45's and I would like to know if there is any truth to this 26-inch diameter rule and what is their experience or troubles with 235/45-17 on a 7.5 width rim on our Maximas. Thanks for your help.

Thanks for the input. The tire calculator shows that the diameter between the 225/50-27 and 245/45-17 are about even. Would there be any issues using the 245/45 on the Max? Just wondering why the TR rep didn't mention the 245/45 as an alternative also. Thanks.

So at 7.5 wheel width I should be fine with the 245/45's. Any turning or rubbing issues to be aware of. Getting my ducks together for another go at it when I call TR tomorrow. Want my rims and tires.

on a 17x7.5 you DEFINITELY will want and enjoy the effects of a 245/45 tire...

Ordered my new wheels and tires today. Purchased the 17-inch Moda R6 with Sumitomo HTR+ 235/45-17's. Should have them by Tuesday or Wednesday next week. Anyone interesed in my Borbet Type H 16-inch wheels with brand new Bridgestone Potenza RE950's 225/55-16 (500 miles), just let me know. My signature has a link to the wheels.

so after all this you went with the SMALLER tire of 235/45/17 instead of the better/wider/more proper size of 245/45/17???

Yes I did. After talking to another TR rep, he said I would be fine with the 235/45-17 since they were going on a 7.5 and not a 8 inch width rim. Will let you know when I get them Tuesday.

235 vs 245 is such a small difference. You'd probably barely notice any better performance. According to this tire calculator either size would've fit on a 7.5 or 8 inch wide rim.

Handling benefit
I am using a 97 SE as a track day car and the track we race on has lots of turns. I'm trying to find the tire that will give us the best handling and traction on 7.5 inch rims.
I see that 235/45s and 235/40s will fit but they aren't optimal (based on daily driving conditions). They list 225/50 as optimal. I don't care about aesthetics.
My question is, which tire will give us the best handling? 235/40s? 235/45s? 225/50s?
thanks

Stiffer le sidewall, le better?
But in the end, most meat on the ground seems king.
So look at the measured width of each tire in those sizes before making a comparison.
Should help between your final choice of 40 vs 45 series.
Nice grave dig btw
You should research this topic outside of the .org
