Thank you so much. I found an additional website
Tire Size and Wheel Offset – Decisions, Decisions.
Which explains the effect of changing offsets in a variety of scenarios. I had to give them my email address to subscribe to the blog to get access to the article, but it was worth it. The article explains conceptually the effect of changing offset, and then walks you through 3 different scenarios with calculations and explanations.
They also have an automatic calculator, which was really useful, also. And a lot faster than doing the calculations by hand on paper. But doing the paper calculations helped me to understand the concept of offset better. I finally understood CLEARLY that the offset is something that is built into the design of the wheel, not built into the design of the car.
So, according to their calculator, going from an 8.0 wheel with 34mm offset in the front, to an 8.5 wheel with 34 mm offset in the front, will reduce the clearance between the inner side of the wheel and the strut housing by 6 mm (0.2362 inch) and push the outside edge of the wheel out by 6mm.
Rear: Going from an 8.5 inch wheel with 46 mm offset (stock set up) to an 8.5 inch wheel with 34 mm offset, will increase the clearance between the inner side of the wheel and the rear strut housing by 12 mm (0.4724 inch) and extend the outer edge of the wheel out by the same amount.
A super useful calculator. Great explanation of the calculations also, on the first website I showed you.
Once again, thanks for all your help.
