18s, 19s, etc.?

[TJeno]

Hey guys. I want to be ordering some American Muscle GT500 Replicas for my GP once I get a few more mods on..and I was wondering about your input on wheel size. They'll only be on the car in the dry (as in, no snow) seasons, but I wanted to know some of the effects of wheel size on our GPs. I know the rims are, the more they affect the transmission, but what's the difference for mileage and such for 18s or 19s, vs my stock (16s?) rims? Will they have a major affect on my transmission only being on for about 60-70% of the year? How can I expect my car's performance to be affected? And lastly, which looks better? (I realize it's an inch of a difference, but different strokes for different folks.)

The performance will be a result of the weight of the wheel/tire combo.

19's will rape you on tire price. 18's are a butt load cheaper.

 

[Bio248]

19s look awesome, but 20s are cheaper and look more awesome.

 

[hockeybawler]

Not trying to thread jack but would it even be worth it to get 17's? And would they be cheaper then getting 18's?

There really aren't any good tires in any good sizes.

18x8 wrapped in 245/45's are "easier".

 

[Bio248]

19s:

$700 in tires.

just get 18s or 20s, both will be cheaper and easier in the end.

 

[TJeno]

Well, rims and new set of Pirelli's, I found a 4-set for $1300..and that should last me a while for only having them on for 60-70% of the year. Those were 19s, I haven't looked into 18s. Also, how would you guys go about lowering my car? Eibach springs?

How much cheaper are you guys thinking the 18s would be? I don't feel like going with 20s, it seems like the 19s or 18s would be big enough/enough work as it is.

 

[Bio248]

my car above was on eibachs. they are the spring i like to recommend.

 

[Fatboy501]

Looks good. I wonder what 20s on Intrax springs looks like.

 

[TJeno]

my car above was on eibachs. they are the spring i like to recommend.

Sits well, what'd you pay for 4?

 

[Bio248]

On the car when I bought it, dunno.

Lucky you.

18's will hand down be cheaper, 19's are the most costly tire out there, very few companys make that size.

Read up on lowering your car and you'll figure out what you need. (struts, mounts, anti pogo washer, spacers, springs etc etc)

 

[blakgtp]

i got eibachs for $230 on ebay. gr2/exel-g struts for around $270, antipogos $25

so around $525. and i bought a spring compressor tool for $39

The website wheel calc. I referenced said, 245/50 17 fits on 7.5"-9" wheel, & has same outside dia.--26.7". Tirerack has Kumho for both 245/45 18 & 245/50 17 & 245/50 17 are cheaper.

Is fitment info true? Is it safe to run 245/50 17 tires on 17/7.5 wheels?

 

[Bio248]

yes, that'll fit fine.

 

[Mr D]

yes, that'll fit fine.

Thanks, good to know.

 

[matt5112]

I didn't see any cool tires in that size for a decent price, hence suggesting opting for 18s.

 

[Mr D]

For tires, I am looking for all season. tirerack has kumho ecsta 4x; 245/50 17 =$136, & 245/45 18 = $165.
