That's a 'fat' setup. Check rom's fitment guide for a closer match in size, in which case you won't be too far off with your speedo. Not sure how it throws off your GPS as a satellite monitors where your car is and has nothing to do with wheel/tire size. If you do go to 19's, make sure you order more aggressive offsets than stock so it fills your wheel-wells better, thus giving you the 'look' you want to achieve. GL.

If you go to 19's you shouldn't keep the 45 profile tires. You'll need to go to a lower profile. The profile you go down to depends on the width of the tires you go with.

For example a 255-35 series - 19 inch tire will be the same as stock and won't effect your speedo (or maybe less than 1mph). A 275 width - 30 series 19 inch will also give you the same overall height as stock. If you want to stay with 245 width you'll probably need a 40 series. There are tire calculators online that you can use to figure it out.

I would probably try to stay with 255 - 35 series if you are trying to keep all the tire the same width so you can rotate them. I think most people on here go with a staggered setup (different sizes for front and rear).

The wheels you buy will effect what you can use too. Each wheel has a different offset. There is a sticky here about wheels that will tell you what offsets and tire sizes that will work for the sc430.

Buying wheels and tires takes a lot of research and time. Be patient.

Romni, I bought 5mm h and r spacers for my front wheels. Is there a proper way to get them to center. They shake like a bad balance even though I've had the tires balance a few times.

The 5mm spacers do not allow for the wheel centering hub to work properly since they do not have a built in lip.

I was thinking of getting the 10mm spacer that has the lip built onto the spacer instead. What do you think?

My steering wheel does get pulled quite easily from road deformities with the 5mm spacer and 19X9.5in wheels with 255X35X19 tires. Will this get worse when going wider (less offset)? When I put the stock wheels without the spacer on for winter there was no pull.

I'm also thinking about buying a spacer for the rear. Any suggestions on how big it should be? I have 19X9.5in wheels with 275X30X19 tires on the rear. I would like the wheels to be as close to flush as possible without having to modify the fenders.

Thank youl

Whar would be a good place to browse for rims that accepts the TPMS sensors?

I tried Tirerack but they don't seem to have the wider 19" that I would like.

i finished up the guide and posted it up, hopefully it can help members. it will be integrated with my old guideline soon
Rominl

I have read your guide and is super of you to do for every one.

I did not however see what I am trying to put on my SC430.

F Rims 18x8.5 F Tires 245/40 R18
R Rims 18x9.5 R Tires 275/35 R18

Will I have any rub that you know of as I am taking the old TPMS out of the stock rims and is going to be quite pricey to mount and unmount. Will this set up be worth it?

Thanks

well this is all good...

but for those of us that are driving this car as a sunny day ride and dont want to spend the bux on 19's or 20's...

ROM doesnt like 18's and that cool. im just a cheap sob and wanted minimum output of $$$

18's are plenty tall in my opinion and you can still have "some" sidewall sqwish.

i am trying 18x8 +38 on the front. should bring the wheel out 3/8 of an inch toward the fender. 245/40/18 falken 452

rear 18x9.5+35 again will bring the wheel out3/8 inch plust 3/4 of an inc because of width so 1 1/8th toward fender. 275/35/18 falken 452

will post pics when they arrive?

TOTAL price mounted, balanced, hub centrics, lugs and delivered...1200$ we'll see how it works.

UPDATE: everything bolted right up offsets worked about perfect for the look i wanted. now the car needs coilovers...

Any progress pics?


Right now my setup is 19x9 +19 and 19x11+23 and fitment to me looks pretty damn good. Do you want the wheels to be flush?

i unfortunally cant show pics until its done. part of the sponsorship, but i am trying to purchase wheels now so they can be made by completion. i am simply extending the kit OUTWARDS, so i just need the wheels to sit under the car but increase the lip. make sense? any help is appreciated.
thanks

What wheels are you considering? Trying to see what offsets they have.
