Rim question
I have found a set of 17x9 with -8 offset rims for a song and dance. Which works out to 4.75" of backspacing.
The tires I want to run are 245/65r17 which are 29.5" on a 7 inch rim. So maybe 28-28.5 on a 9 inch rim. My C10 has 30x9.5r15 on 7 inch rims with about 2.5 inches of room left till the tires hit the fender lips level. Would the front tires clear with a 2" drop, and allow decent suspension travel or should I keep on looking? |

Re: Rim question
Can’t answer your question but gotta say tires don’t change height with different rim widths.

Re: Rim question
Yes they will. Depending on how different the rims are, and tire construction. Some tires are more prone to changes due to the sidewall construction.
Carcraft did a article where they changed tire height on 30" slicks by going from a 7" to a 10" rim by 2 inches. |

Re: Rim question
Of course!
Slicks! No sidewall like a street tire. Totally different animal. |

4x4 guys often run a narrow rim to increase rim hold or what ever it is called when aired down. It has the effect of squeezing the tire taller.. |

Re: Rim question
This article says tire width is changed by approximately 2/10" for every 1/2" change to wheel width.
https://www.tyresizecalculator.com/c...rim-size-chart It would make sense that the tire would get taller as the wheel pinches it narrower. The material has to go somewhere.
