Fluctuations in the rolling radius are an everyday occurence (even with pressure monitors).

All speedos are innacurate by some degree - a speedo that reads true at 30mph will not be true at 70mph & vice versa.

As long as you are there or there abouts everything will be fine.

If swapping out aim for somewhere near original, but don't be too much of a stickler for the exact match

F = 775.0 to 784.0
R = 754.0 to 768.0

Also, don’t forget that the offset figure refers to the offset of the mounting surface & does not determine the clearance for brake calipers & suspension parts. This clearance dimension will depend on the specific wheel design & any modifications made to the vehicle suspension & brake setup.

If anyone else has tech info relating to specific brands & ACTUAL setups please post.

Please no photoshops, or wishlists - this stuff needs to work on the vehicle - get my drift???

Keep it positive…
