I understand 45 offset in the rear is fine for 18' wheels. But what if the only two choices in the front are 35 and 45 offsets. Would any of these work on a 18' 8.5 front? Thanks in advance.

Look at the stickies in the MKIV Tech section. There is a wheel fitment guide there. Please put something wider than a 8.5" wheel on the front. At least go with a 9" wide front wheel. I would recommend a 255 on a 9" wheel as the narrowest tire/wheel to run on the front of a MKIV. BTW you could run a 255/35R18 on an 18x8.5" 45mm offset. It is not the best setup however.

Steve you are the MAN!...just wondering...why if the supra was so expensive when new....why didn't they go with a bigger front tire to begin with? You sound like the car should have came bigger....I'm pretty sure vettes use 275 front and rear...??? Why not the supra?

Everything is a compromise. Most manfacturers skimp when it comes to wheels and tires. Here is a retail comparison (though manufacturers would be dealing with lower wholesale values. You can buy a nice set of 17" cast aluminum wheels and top notch Michelin tires for $1,800. If you go with a top notch wheel/tire combo in the appropriate sizes and same tire brand/model the cost would be $4,100. That is a difference of $2,300. That is quite a lot to add to the cost of the car, considering it's almost 6%. Most people can't appreciate the difference especially when they are comparing a 300ZX or RX7 to the Supra, when it was quite a bit more expensive already. Think about the lateral G's the Supra pulled with the stock setup. It was already way ahead of it's competition without the bigger wheels and tires. Your same question could be asked about the turbos. Why didn't they use a nice size single instead of the stock twins. Imagine a 500 crank hp Supra right off the showroom floor. :) It's all about compromise. Just be glad they put the money in a strong engine and drivetrain.

Thanks for the info Steve. I really want wider rims front and back but the maker only offers a choice of 8.5 and 9.5 wide rims with both offset choices being 35 and 45. That's why I'm considering running the 8.5 for fronts and 9.5 for rears. If I do purchase these rims and go with 255/35R18 for the fronts, what would you recommend for the rears?

I would go with a 285/30R18. I am not sure why you would want to spend so much money to basically go with stock sizes, but hat is your decision. You can at least go with an Enkei RPO1 in a 9" front and 9.5" rear.
