Is there a way to +1 and avoid squirm?
Hello,
How can you +1 your tires and not have squirm and keep it stock? Some history, I have done this a couple times, once with a 4 Runner on all 4 tires and it was awful. Tried it on my S, rear only to a 255/40x17 and it is not unbearable, however it is noticeable (front is 215/45x17). The cons are straight line squirm and requires a slight amount more accelerator to start. The pros are handles better cornering and looks good. Am I wishful thinking?
I assume most are changing to a lighter weight wheel and altering the suspension when going to oversized tires. I appreciate any of your suggestions or direction.
Thank you,
Michael

Hi,
Referring to one size up on tire size width, the stock/OEM rear size on the AP2 is 245/40x17. So, going from a 245 to a 255 in this scenario.
As I understand, basically any tire can be upsized by on size without having to change the wheel size on any vehicle. Perhaps I am wrong.
Trying to find some input as some owners do more than +1.
Thanks.

What tires are you getting squirm with?
255 rear tires: These are CR tire size. All the CRs use the same wheels as the "base" cars and run 255 rear tires retaining 215 on the front. I'm running these same sizes the past three years. Not a hint of squirm from the Bridgestone S-04 tires on OE wheels. Tire circumference is a tiny bit larger. The 255 tires turn 832 revolutions per mile compared to 843 for the minutely smaller diameter 245 tires. That's a 1.3% difference and not enough to upset things like anti-lock brakes, etc. It's also not enough to have any real effect on acceleration, etc.
("Plus 1" to me implies 1" larger wheel diameter, not tread width. Honda 17" wheels will replace Honda 16" wheels without modifications and you can run base or CR-spec tire sizes.)

In 10 years, I have had Kumo burn them up in no time, Conti DWS were OK but no snow in Texas, then Michelin SS and replaced them with Conti EC. Michelins were really nice and use Michelin Premier on the DD, just did not think I needed to put that expensive of a tire on the S to not drive it much. Would definitely buy the CEC again, just probably not the next size up.
I am anal when changes are made on my cars, especially the S and thought it curious that some may run 265, 275 and larger and no mention of squirm.

I'd avoid these All Season tires if you don't want squirm.

Yeah you need to look for tires with stiffer sidewalls with more layers. A wider wheel where the tire is less pinched would also help but you want to keep it stock. I'd also have the alignment checked.

Continental ExtremeContact Sport and Bridgestone Potenza S-04 Pole Position are sold and advertised as "Performance/Summer" tires by Discount Tire. Chuck, thank you and I will consider your recommendation; however, I would like to know if there are any other options and if others may have had this happen.
Sorry, Manga, would you be more specific as brand for stiffer, more layers? Just had the alignment checked, like a day or two before getting the new tires. It is sounding like I may need to eat these CECs, lol.
I am still trying to understand how someone can square a 255/265s or stagger 305s on the rear and not have some squirm.
Thank you all!
