SO i got the 15 inch rims finally sand blasted and painted a nice white and i was wondering if 205/55-15 rims would be a good size ?
-
The 94 XR2 uses 195 50 tires without any problems you might run into clearance problems with the strut seats with 205's unless you have coil overs.
-
I have 205/50 15 on the rear of my 94 xr2. Never had a problem. They are worn out but thats from the road not the struts!Rocky
-
i'd say go with stock size 15 tires for the capri. to keep the speedo close. usally the 14" and 15" tires are set so they can be swapped without much speedo change. bigger question, most aftermarket rims are wider then stocks when people get them. how wide are your rims cause normal xr-2 tires might not work right with the width.
-
I find this website very helpful when figuring out tire sizes.

that calculator works well. but before you do it. find out how wide your wheels are, and then find out the different sizes of tires that are possible to get for that wheel thickness. once u get them, use the calc to measure your standard tire to the ones avaliable for your aftermarket wheel size and get the closest size with the least difference on your mph.

here are all the tire sizes that will fit without problems and keep your speedo right

im on my second set of wheels for my capri. both have been 16x6.5... and making close to 200whp im allways searching for traction..what ive found is a 205-40-16 fits all the way arround
giving about .5 inch between the rear lower spring stops and the tire.... a 215-45-16 will fit in the front, leaving about the same .5 inch
to the spring stop....ive got a set of 3/8 wheel spacers from a past b6t festiva build (needed to clear 205 on the festy) with theese and some longer gorilla studs im going to run 215-45-16 all the way arround.... should help traction issues encountered with the power of the new
engine we built... and give a sportier appearance with the wider stance....just thought id toss my setup out there ....
-
those sizes still depends on widths. of the wheel itself. also the speedos will get set off some. look at the 16" wheels
205/40-16
215/40-16
both use the same % of side wall, just one is 10 more then the other. so that 215/40 will set the speedo off more then the other.
-
ok, first on a car with a quick detach bumper (for intercooler servicing) and 200 ponies, im not caring much if the speedometer reads correct. with the first 60 mph flashing buy in mere seconds, your speeding.. and thats all ya really need to know.
a 215 40 16 does not exist. (well not in kumho land) to get a 215 width you need to take the 45 series aspect ratio in trade. the 215-45-16 is a taller tire when inflated than the 205-40-16 is
not able to be put on the capri, without wheel spacers or a wheel with more dish. the rear spring seats rub the tires...

(http://i258.photobucket.com/albums/hh278/RCIfabrication/PICT0772.jpg) and theres how much my wheels and tires clear the strut
-
thanks for the input from everyone i have decided because i already have 2 185/60r15 i will go with that size which is whats on my car right now.
P.S rcicustoms where did you get that rollbar type thing behind your seats i was looking to get one.
-
You can get the miata roll bar and it will fit near close. im not 100% sure about the mounts, but im sure you can get something to match.
-
the miata style bar will fit with modification ...you will need a grinder... and you need to modify the top compartment lid it needs the corners cut off...its not easy but not all that hard one drawback is you cant run both the style bar and a bubble tonneau you have to make a small tonneau... (http://i258.photobucket.com/albums/hh278/RCIfabrication/PICT0747.jpg)
heres a better pic ...you can see where i had to trim the corners off the top cover lid. but just a little bit... the bar bolts under the seatbelt shoulder belt retract guide...
-
How much of the corners will you need to cut off and if possible could you give me a top view picture ? Also what is the plexi glass that i see ?
-
Thats excellent, I was going to try the same thing but I ended up getting a really good deal on a bubbletop (tm)
Looks really awesome man
-
I think it will turn out pretty good i will be doing that project soon and ordering the miata roll bar tonight for 40 bucks and will be doing some other small things pictures will be up soon
-
the plexi glas is a wind deflector... it allows a conversation at highway speeds with the top down ...its raining right now... but when it stops ill post a pic of the top compartment lid and how much was taken off.. its not much
about a half moon half the diameter of the bar.
(half of a 2.5 in circle) when your top cover lid is open. you can remove the grey surround by taking the nuts off from the inside ...its easier to cut if its off..ill send pics soon ...be good ..joe
-
Looks great man, Can you take a pic of how it mounts as well?
-
Also could i get the dimensions of the roll bar please. -Josh

Hello all,
Lazy as I am, can anyone tell me the fatest, tallest tires I can put on the standard 15" wheels on my 1993? It would be nice if the speedometer & mpg are not too affected...
Thanks!

Be careful with the tire sizes as the plus sizes with multiple listings are for different wheel widths.
-
what does "plus zero" mean,
i want to put 205/50R15 r-comps on my capri for autoX but i need to know where i can get rims, I have a spare set of OEM 1991 Rims
-
All Plus zero is, is the default wheel size to start from. so if 0 is the starting OEM rim size, each plus after is next inch size of for a possible fitting rim.
-
so basically there are 2 size of 15s you can use without messing up your speedo. those are all the sizes that will fit and keep the cars speed correct

Going over the tire size chart which really helps, I was wondering if going with 205/45-16's will fit with the regular struts? Hopefully I don't need coilovers since my struts are new. I don't care about the speedo being off, I just want traction. Hell, I speed everywhere I go anyway.
-
this website should help a bit. www.miata.net/garage/tirecalc (http://www.miata.net/garage/tirecalc)
-
So as long as the calc. comes up negative I'm good as long as i take wheel width into consideration. I'm going through Tirerack.com for the widest range of rim widths. Since this is a major purchase I want to make sure so I don't have a set of rims & tires to sell at a loss.
-
make sure you look at the off set also.
-
A lot of different answers on this whole subject. Looks like trying to keep the offset as close to original will work? But I'll be reading for awhile still. Someday most of these tire & wheel size threads with the offsets all in one will be the ultimate sticky. I def. don't have the talent(knowledge) for that one. Thanks, Rob
-
I have OZ Racing wheels on my 323's ...they are 15x6" w/ 46mm offset. The bigger wheels will need less offset....around 38-40 I would think for 17's. The biggest wheel I would put on a BF based car would be a 16 with like a 205/45's. But remember that the bigger wheels will raise the center of gravity and you will need to use drop springs or coilovers to bring it back down. This is where the offset comes into play so you don't end up rubbing the fenders.
