Effects of Lower Offset / Wider / Lighter Wheels

Hi Everyone!

This is a subject that is sort of getting discussed a lot. I really want to get everyone's and any expert's idea of what are the effects of lowering the offset.

Do you guys also think that a lighter wheel and tire setup will only be beneficial or could this by any chance affects the balance of the LSD the the torque steer that seems to be the main issue.

What about a wider wheel or tire setup? I'm thinking 9" or even 9.5" will work, but to what result and outcome?

Thanks for all your feedback and responses! Hope this becomes helpful

BTW our stock wheels are

20x8.5 ET60



I also just learned that our TPMPS is a sensor located in the ABS system

"The sensors are located in the ABS system, and are speed sensors. Once one tire loses pressure, it will spin at a different revolutions per mile, which will then trigger the low pressure warning light."

Thanks for that info- thats very interesting.

The R contains an "indirect TPMS" which is fairly standard across all Honda vehicles. This is a good thing for those who enjoy swapping wheels.

The question that I have in relation to the post is: What is your end goal? What are you trying to achieve by swapping wheels for something lighter and wider? If performance is what you are looking for, it is my opinion that the R is going to take A LOT of driver to outperform the vehicle in factory form, outside of a simple tire and brake pad swap. -This is actually something that has me really attracted to the R. It is a complete showcase of Honda engineering, all in one package.

Great points, what about if you swap a tire for a winter wheel set up. You no longer have the same width or tire diameter. Will this set off the TPMS?

When I swapped my stock rims/tires for lighter aftermarket rims/tires, I reset my TPMS on the radio. No problem at all.

The computer is measuring revs per mile. Once one tire is rotating a different rev per mile, the system will trigger the warning. It doesn't matter if you put on 35" mud swamper tires or 15" temp tires....if they are all four rotating at the same revolution speed, the TPMS will not detect it.

This is one reason I really dislike TPMS in general. If all 4 tires are under or over inflated, the TPMS will never detect it.

To avoid affecting torque steer, you would want to reduce offset by half the amount of wheel width you add.

That's not to say that it will torque steer like a Mazdaspeed3 if you didn't do it exactly, but that's how you would keep it at stock levels.

So, going to a 9.5 inch, 1.5 inches wider, which is about 38mm. So you need to reduce offset by 19mm, to a 41? Is my thinking correct on this?

It would be 1" wider so about 13MM less in offset.

Although I'm no expert, this actually makes sense, since it'll keep the centerline of the wheel in the same spot.

So 42mm offset?

60 minus 13 would be 47

a 9.5" Wide Wheel at 47mm Offset

Would it be a 9.5" wheel with a 35mm offset?

you are right.

Crap, I was thinking it was 8" wide. my apologies...

So they cheap out on the sensors. No individual pressure reading
