I am looking for a new set of wheel/tire packages online but i am unsure about ordering. They all say 100% fitment or your money back. I have an '89 toyota supra and it origanlly had a 4 lug nut design but all four have been changed to five. i dont know how to measure or figure out what kinda of wheels would fit.  

When you got the new hub flanges, you should have paid attention to the size of the pattern. If the hub flanges are from another Toyota or an after market design made for it, then, it's most likely a 5x114.3 pattern. That's Toyotas fovorite size. Ford and Mazda use the same pattern size on certain models. Don't take my word for it, though. You're better off asking the people you got the hub flanges from. They can answer you better, if they are after market.
And I would wait till winter to buy tire and wheel packages. They are extremely cheap around that time. I've seen 18" wheel and tire packages for $900.00! I would think about it first and not spend so much when you really don't have to.  

I had bought the car a couple months ago and relized that it was different from stock specs. Thanks for the new infomation again.  

I'm glad that I can help. Take it slow, though, if you plan ahead with out considering what else was changed from stock, you'll find that the headaches get bigger. Try to find out what is still stock and what was changed before getting in too deep so your not left scratching your head in the process.  

Thank you again BM your really making it easier on me  

Your best bet is to take the car to a local tire shop, and they have a tool designed to measure bolt patterns.  They'll be able to tell you what it is, and after that you'll be able to order wheels that will fit.  Take into consideration ride height as well.  If the car has been lowered you may not be able to fit the size wheel that you want.  

You can measure from the center on one hole to the BACK of the third hole.This is the easiest way to measure a 5-lug bolt circle. I used to change oil and tires at Wal-mart (don't laugh)    

Work is work, Curtman. Any body that would laugh at some one who works, instead of lazying around, deserves a hammer to the head! Do not belittle your work experience or where you work from, period. Be PROUD that you're working and not selling poison on the streets! I don't belittle people that work hard for their honest money, and no one else can either!
I should have thought of this before...On the search bar you can type "bolt pattern gauge" and a slew of links will come up to guide you on your way to purchasing a tool that will end your search. There are very helpful techs out there that will help you determine the size of your bolt pattern but some times doing it your self is more rewarding. Your choice.  

OK cool you guys are realy helping a lot  

We try. We may not be the end all be all of information but when we tuners get together we get things done! I still need to figure out women, though!  

LOL Theres a lot of things i need tofigure about this car tho  

I'm really trying to help you as much as possible. The unfortunate thing is that the age of the car is hindering any viable possibilities. I'm on the same boat as you with my 87 200sx. It's a s12 Z-body platform and there is only so much that you can find for that as well... We should start a new club called "The hard to find parts for cars club!" OOOORRRRRR, maybe get into the old Japanese car parts manufacturing buisness! LOL!  

Thank you so much. I understand. itsold and parts fall off the map (Fast) but i know at the local pick a parts they parts and i went to check 89 7m gtes cause on the internet it said there was 2 i found and both were cracked but for 2 dollars you know haha u get what you pay for.  i kinda that stuff for friends in high school right now blackmonkey. ive helped them find parts for some of their dads dads wifes brother uncle cars like an old fairlady and a starlet pick a part and swap meets we spent 4 weekends trying to go through everything i they got what they wanted and i didnt even have a car! but i got one now and history is sure repeating itself . . .again.  

I feel you 100% on that subject...
My car got removed from my garage by my caniving, impersonating cousin, well... he orchastrated it at least. My car was located on the shipping docks in Miami. I don't know Miami to save my life, so I don't know which docks my boys were reffering to. I took a trip to see it and it was mine alright. The dudes that were trying to ship it to Puerto Rico sold my cousin out with out a fight what so ever. From there I took a plane to Puerto Rico and confronted my cousin, with some law enforcement buddies of mine, that live there. He couldn't deny the facts that were presented to him. Now I think that this little thing he did will help me whith the case he has against me. I sorta' busted up his hands really bad the last time for impersonating and stealing money from me. All's well that ends well!
I'm happy that you're making head way on your car. I hope you get every thing you need. There aren't a lot of old school import rides around any more. Save for the few Skylines and Datsun 240Zs, and the like.  

Hell ya. I got another thing about my car i was reading in a performance book by haynes that since i have new rims and tires and with a bigger wheel radius that it can through the speedometer off and now its not working i cant seem to figure out what is wrong with it. Can you help me with all the likely problems?
